`_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.

Most block feature checks are for a single feature string, and for such cases it is not intuitive to require an array for the `$feature` parameter of the `block_has_support()` function.
This changeset brings it in line with other functions like `post_type_supports()`, allowing to pass a string for the `$feature`. An array is still supported for more complex cases where support for sub-features needs to be determined. This change furthermore includes a very minor performance tweak by avoiding calls to the `_wp_array_get()` function if a single feature string is being checked for.

Backports https://github.com/WordPress/gutenberg/pull/46074 into the core.
render_layout_support_flag is run per block, and inside we called get_global_settings three times. get_global_settings calls get_merged_data, which is costly. render_layout_support_flag is a filter called during the block render. When the blocks start rendering, there is no expectation that the theme.json settings change during the block render, so the settings and their derived information should all be static information of this function.
This simple change removes 3*NUMBER_OF_BLOCKS calls of get_merged_data to just one call.

Adds `wp_theme_has_theme_json()` for public consumption, to replace the private internal Core-only `WP_Theme_JSON_Resolver::theme_has_support()` method. This new global function checks if a theme or its parent has a `theme.json` file.
For performance, results are cached as an integer `1` or `0` in the `'theme_json'` group with `'wp_theme_has_theme_json'` key. This is a non-persistent cache. Why? To make the derived data from `theme.json` is always fresh from the potential modifications done via hooks that can use dynamic data (modify the stylesheet depending on some option, settings depending on user permissions, etc.).
Also adds a new public function `wp_clean_theme_json_cache()` to clear the cache on `'switch_theme'` and `start_previewing_theme'`.

This commit merges the remaining changes from [https://github.com/WordPress/gutenberg/pull/40875 Gutenberg PR 40875]. It's Part 2 (see [54162] for Part 1) of a layout improvement initiative and targets `wp_get_layout_style()` in `layout.php`.
Context:
The overall initiative is to improve layout block support:
>to use centralised layout definitions, output base layout styles from global styles, introduce a layout type semantic classname, reduce duplication of container class and style tag output, and fix blockGap at the block level in global styles.
Changes include:
* Adding an optional parameter `$block_spacing` to `wp_get_layout_style()` for setting a custom spacing on the block.
* Adding handle for the block spacing.
* Using the style engine to to enqueue and render layout styles via `wp_style_engine_get_stylesheet_from_css_rules()`.
* Introduces a new test file for `wp_get_layout_style()`.

Previously, `safecss_filter_attr` did not allow for `calc` and `var` in parsed CSS. Because of this, `wp_strip_all_tags` was used in `wp_get_layout_style` to allow for the use of these CSS functions to account for responsive widths. [50923] added support for both of these CSS functions in KSES, so `safecss_filter_attr` can now be used in `wp_get_layout_style` as originally intended.

The dynamic block styles for layout and elements should be loaded in the head for block themes. While that should also be the case for classic themes, the current mechanism we use (render_block) does not allow us to do that, hence, this PR doesn't change anything for them and will be loaded the body.
