Previously, the `variations` field in a block.json file could be used to provide a static list of the block's variations (i.e., an array). Alternatively, the block's `variation_callback` could be set during server-side block registration to point to a PHP function to generate those variations.
This changeset makes it so that the block.json `variations` field can be alternatively set to a string, which will be interpreted as the filename of a PHP file that generates the variations.
It is loosely modeled after [54132], which introduced the `render` field for `block.json`, as a way to point to a PHP file instead of providing a `render_callback`.

The Block Hooks mechanism was previously extended to allow insertion of a block as a Navigation block's first or last child. This was implemented by storing the `ignoredHookedBlocks` array in the corresponding `wp_navigation` post's post meta (instead of a metadata attribute on the anchor block).
This changeset extends that mechanism to Template Part blocks, by storing said metadata in the corresponding `wp_template_part` post's post meta, thus allowing extenders to use Block Hooks to insert a block as a Template Part block's first or last child, respectively.

Prior to this changeset, the function `update_ignored_hooked_blocks_postmeta()` used the core function `update_post_meta()` to write `_wp_ignored_hooked_blocks` data to the database during an operation that is preparing a post to be inserted.
Since we have access to the incoming changes that are being prepared we can remove this database operation in favour of writing the data to the post object provided under `meta_input`.
Doing this means two things:
1. It allows us to store postmeta for new posts that are about to be created since they don't have an `ID` yet (which is information `update_post_meta()` needs).
2. The core controller will take care of updating postmeta in a more predictable pattern.

In a similar vein as [58291], this changeset introduces a new `insert_hooked_blocks_into_rest_response` function and hooks it to the `rest_prepare_wp_navigation` filter.
This is part of an ongoing effort to move Block Hooks related code out of the Navigation block. Specifically, `insert_hooked_blocks_into_rest_response` is based on `block_core_navigation_insert_hooked_blocks_into_rest_response`. Eventually, it will be possible to deprecate the latter.

As of [57790], the Templates endpoint uses the `rest_pre_insert_*` filter to inject the `ignoredHookedBlocks` metadata attribute into anchor blocks, prior to persisting a template or template part to the database. The same principle was implemented for the Navigation endpoint (where additionally, first and last child blocks added at the top level are store in the `wp_navigation` post object's post meta). The required logic was added to the Navigation block's code, i.e. inside the Gutenberg code repository, and then synchronized to Core.
In order to harmonize the code between the two endpoints, this changeset introduces a new `update_ignored_hooked_blocks_postmeta` function, which is based on the Navigation block's `block_core_navigation_update_ignore_hooked_blocks_meta`, alongside a few helper functions, and hooks it to the `rest_pre_insert_wp_navigation` filter hook. (The Navigation block has been prepared in [58275] to add an additional conditional to check for the new `update_ignored_hooked_blocks_postmeta` filter so there won't be any collisions.)
Eventually, this will allow to deprecate `block_core_navigation_update_ignore_hooked_blocks_meta` (and some related functions), and remove the relevant code from the Navigation block. It also paves the way for some other future changes, such as inserting a hooked block as a Template Part block's first or last child (#60854).

The Block Hooks UI relies on the `ignoredHookedBlocks` metadata when determining whether to show the toggle in the Site Editor. The problem is that for uncustomized templates we don't add this metadata.
Currently the visitor functions have a default callback of `insert_hooked_blocks` and we only add the metadata when we're writing to the database via an available filter in the template controller.
This changeset creates a new callback which both inserts the hooked blocks and adds the `ignoredHookedBlocks` metadata to the anchor block, and uses this new callback explicitly in the visitor functions that are run upon reading from the database.
We continue to set the `ignoredHookedBlocks` metadata when writing to the database, i.e. this operation happens twice. Although not ideal, this is necessary to cover the following scenarios:
* When the user adds an anchor block within the editor, we still need to add the `ignoredHookedBlocks` meta to it to prevent hooked blocks hooking on to it unexpectedly on the frontend. This is required to keep parity between the frontend and editor.
* When a user writes template data to the database directly through the API (instead of the editor), we need to again ensure we're not inserting hooked blocks unexpectedly.
It is worth noting that with this change, the first hooked block to insert relative to its anchor block will be accepted. Any additional blocks of the same type (e.g. a second `core/loginout` block) trying to hook onto the same anchor block will be ignored, irrespective of the position.

Decouple hooked blocks insertion from setting the `metadata.ignoredHookedBlocks` attribute on anchor blocks, and perform the latter step upon saving a template or template part to the database. This ensures that anchor blocks that have been newly added to a template (or part) on the client side will also get `ignoredHookedBlocks` metadata set correctly, thus preserving editor/front-end parity. Hooked block insertion, on the other hand, will continue to happen upon ''reading'' a template (or part).

Add a new `hooked_block_{$block_type}` filter that allows modifying a hooked block (in parsed block format) prior to insertion, while providing read access to its anchor block (in the same format).
This allows block authors to e.g. set a hooked block's attributes, or its inner blocks; the filter can peruse information about the anchor block when doing so. As such, this filter provides a solution to both #59572 and #60126.
The new filter is designed to strike a good balance and separation of concerns with regard to the existing [https://developer.wordpress.org/reference/hooks/hooked_block_types/ `hooked_block_types` filter], which allows addition or removal of a block to the list of hooked blocks for a given anchor block -- all of which are identified only by their block ''types''. This new filter, on the other hand, only applies to ''one'' hooked block at a time, and allows modifying the entire (parsed) hooked block; it also gives (read) access to the parsed anchor block.

The biggest tradeoff that was made in the implementation of Block Hooks was that they were limited to layouts (i.e. templates, template parts, and patterns) that ''didn't have any user modifications'' (see #59313 for the reason). This changeset is a preparatory step to remove this limitation, so they’ll eventually also work with user-modified layouts.
The crucial problem to solve is how to acknowledge that a user has opted to remove or persist a hooked block, so that the auto-insertion mechanism won't run again and inject an extraneous hooked block on the frontend when none is solicited.
This is achieved by storing all known blocks hooked to a given anchor block in the `metadata` attribute on that anchor block; specifically in a field called `ignoredHookedBlocks` inside of the `metadata`. Hooked blocks are only rendered on the frontend if they're absent from that field; OTOH, they're injected into that field (via the REST API) when first loaded in the editor.
This simple logic guarantees that once a user modifies a given layout, those changes are respected on the frontend; yet if a plugin that includes a hooked block is activated after those modifications have taken place, the hooked block will be rendered on the frontend. This new technique supplants the one previously used (i.e. rendering hooked blocks on the frontend only if a layout doesn't have any modifications) in a rather direct way.
Note that this changeset only introduces the new metadata field and relevant logic; it does not yet enable hooked block insertion into modified layouts. That will be done in a subsequent step (see #59646).

The callbacks returned by `make_before_block_visitor` and `make_after_block_visitor`, respectively, (which are passed as arguments to `traverse_and_serialize_block(s)`) currently accept three arguments, all of which are block arrays (i.e. with properties `blockName`, `attrs`, etc.):
- A ''reference'' to the block they're currently visiting, `&$block`;
- the block's `$parent_block`; and
- the `$prev`ious block (for `make_before_block_visitor`), or the `$next` block (for `make_after_block_visitor`), respectively.
Those arguments are passed to the "block visitor" callbacks by `traverse_and_serialize_block(s)` during traversal. The block that the callback is currently visiting is passed ''by reference'' to allow modifying it, which is e.g. used to inject the `theme` attribute into Template Part blocks.
One major limitation of Block Hooks is that they currently only work with templates, parts, and patterns that ''don't have any user modifications'' (i.e. that come straight from the corresponding theme files, rather than from the database). For WordPress 6.5, it is planned to change that to make Block Hooks work for templates, parts, and patterns that ''do'' have user modifications: #59646.
This will be implemented by storing an attribute on the "anchor" block. While working on that feature, it was found that the aforementioned callbacks will need to modify not only the currently visited `$block`, but also the `$parent_block` -- i.e. that the latter argument needs to be passed by reference as well. This is consistent with the requirement of adding an attribute to an anchor block, as it's not only the currently visited block that can serve as an anchor block (in the case of `before` or `after` sibling insertion), but also its parent (for `first_child` and `last_child` insertion).
If the `$parent_block` argument were to be changed to become a reference in a later WordPress version, this could be considered a backwards-compatibility breaking change. For this reason, this change is instead proposed for 6.4 already, which is the cycle during which the relevant functions were first introduced. This should have no impact on existing code, since nothing currently relies on `$parent_block` remaining unmodified by the respective callback, nor is anything currently modifying that argument.

Both the `$pre_callback` and `$post_callback` functions that are given as arguments to `traverse_and_serialize_block(s)` receive a reference to the current block as their first argument. However, while any changes that the "pre" callback makes to the block are reflected by the serialized markup, the same wasn't true for the "post" callback: Any changes that it made were only applied ''after'' the block had already been serialized.
This commit changes the behavior such that `$post_callback`'s changes to the current block are also reflected in the serialized markup.

It was found that Template Part blocks were broken in the Site Editor, showing the `Template part has been deleted or is unavailable` message, due to a missing `theme` attribute.
This bug seems to have been introduced by [56896], whose goal was to only inject that attribute into the markup returned by the templates and patterns REST API endpoints but not on the frontend, in order to improve performance. It has been demonstrated locally that reverting that changeset fixes the bug.

Having the patterns registry inject the `theme` attribute into all Template Part blocks inside every pattern was found to negatively impact performance. It turns out that it's only required for the editor (i.e. in the REST API) but not on the frontend; there, it's instead possible to fall back to the currently active theme.
The latter change was made to the Pattern and Template Part blocks in https://github.com/WordPress/gutenberg/pull/55217, which was sync'ed to Core in [56849]. Consequently, this changeset removes `theme` attribute insertion from the frontend.

In the context of register_block_script_handle, the get_block_asset_url function may return false when an empty string is provided as the input. This behavior is intended to prevent the generation of invalid URLs. However, when the script loading strategy is set to "defer" while passing false, it triggers a "doing it wrong" message.
This situation becomes problematic, especially for scenarios where the scripts haven't been built yet. In such cases, the realpath call returns an empty string because the file doesn't exist. To address this issue, we now perform a simple check to ensure that the script URI is not empty before applying the "defer" loading strategy. This adjustment prevents unnecessary deferral of loading for scripts with empty URIs.

`_wp_array_get()` is an expensive function, and it's called thousands of times on each page view on the front end. While the function performance was slightly improved in #58376, it is still called more times than it should be.
This commit aims to further optimize its usage:
* In many cases, `_wp_array_get()` can be replaced with a much simpler and faster `isset()` check.
* The `isset()` function is capable of checking nested arrays, so `isset( $foo['a']['b']['c'] )` will return false even if `$foo['a']` is unset, without throwing any errors or warnings.
* When `_wp_array_get()` cannot be directly replaced with `isset()`, it would be good practice to wrap it in an `isset()` function so that `_wp_array_get()` only runs when it needs to.
