This is a major release and contains breaking changes.
Most important changes to be aware of for this release:
* All code is now namespaced. Though there is a full backward compatibility layer available and the old class names are still supported, using them will generate a deprecation notice (which can be silenced by plugins if they'd need to support multiple WP versions). See the [https://requests.ryanmccue.info/docs/upgrading.html upgrade guide] for more details.
* A lot of classes have been marked `final`. This should generally not affect userland code as care has been taken to not apply the `final` keyword to classes which are known to be extended in userland code.
* Extensive input validation has been added to Requests. When Requests is used as documented though, this will be unnoticable.
* A new `WpOrg\Requests\Requests::has_capabilities()` method has been introduced which can be used to address #37708.
* A new `WpOrg\Requests\Response::decode_body()` method has been introduced which may be usable to simplify some of the WP native wrapper code.
* Remaining PHP 8.0 compatibility fixed (support for named parameters).
* PHP 8.1 compatibility.

This commit also resolves 2 blocking issues which previously caused the revert of [52244]:
* New Requests files are loaded into `wp-includes/Requests/src/`, matching the location of the library. In doing so, filesystems that are case-insensitive are not impacted (see #54582).
* Preload: During a Core update, the old Requests files are preloaded into memory before the update deletes the files. Preloading avoids fatal errors noted in #54562.

Because themes are updated independently of Core updates, any deleted files from bundled themes should not be included in the `$_old_files` list.
Any file included in this list is deleted on update, which could cause problems for sites with a given theme active if the removed files were required in earlier versions of that theme and that theme is not updated at the same time.

This properly deletes the now empty `src/wp-includes/blocks/comments-query-loop` directory and adds that directory to the `$_old_files` array.
The files in this directory were removed in [54257], but the directory was not marked as deleted in SVN.

Resolves a fatal error due to `get_template_hierarchy()` due to incompatible older Gutenberg versions.
[54269] introduced this new function for 6.1. The function was introduced in Gutenberg 13.9.0. However, it was not guarded to protect the plugin from when the function was loaded in Core. Gutenberg 14.1.0 added the `function_exists()` guard to protect the plugin from the fatal error.
Minimum compatible version:
This commit changes the Gutenberg minimum compatible version number to 14.1. For versions older than 14.1, the plugin will deactivate when upgrading Core to 6.1 or newer.
Function rename:
Past commits renamed the upgrade function by changing Core's version number. This commit renames the function to be generic, i.e. `_upgrade_core_deactivate_incompatible_plugins()` and adopts the `@since [reason]` strategy to track historical changes to the function.

WordPress 3.2 introduced several enhancements to the `copy_dir()` function:
* No more re-installing Akismet upon upgrade.
* Respect custom `WP_CONTENT_DIR` for bundled plugins/theme installation.
* Respect custom `WP_CONTENT_DIR`/`WP_LANG_DIR` for language files when upgrading.
* Add an exclusion list to `copy_dir()` as well as `WP_Filesystem_Base::wp_lang_dir()`.
* Standardize `WP_Filesystem` path method returns.
However, the version of `copy_dir()` that runs during the upgrade process is the one from the older install, not the newer, which means that these enhancements would only be available after upgrading to WordPress 3.2 first, e.g. in a subsequent upgrade to WordPress 3.3.
In order to make these enhancements immediately available in WordPress 3.2, specifically to take advantage of skip lists and avoid re-installing Akismet if it was previously deleted, a temporary copy of the function was utilized, with the intention to remove it in WordPress 3.3 or a later release.
With further enhancements made to the Upgrade API to support partial and no-content builds, this temporary copy is no longer relevant and can be safely removed.

In PHP 8+, `@` no longer suppresses fatal errors:
> The `@` operator will no longer silence fatal errors (`E_ERROR`, `E_CORE_ERROR`, `E_COMPILE_ERROR`, `E_USER_ERROR`, `E_RECOVERABLE_ERROR`, `E_PARSE`).
Reference: [https://www.php.net/manual/en/migration80.incompatible.php PHP 8: Backward Incompatible Changes].
`disk_free_space()` may be disabled by hosts, which will throw a fatal error on a call to undefined function.
This change prevents the fatal error, and falls back to `false` when `disk_free_space()` is unavailable.

Follow-up to [52165] where the `version_compare()` fails for 11.8.x versions. This commit changes the version comparison to < 11.9 for deactivating the Gutenberg plugin.
The `_upgrade_580_force_deactivate_incompatible_plugins()` function is no longer needed in 5.9. It's redundant and unnecessary as `_upgrade_590_force_deactivate_incompatible_plugins()` deactivates those versions as well.
Removing `_upgrade_580_force_deactivate_incompatible_plugins()` and moving the deactivation logic back into the `_deactivate_gutenberg_when_incompatible_with_wp()`, thus removing the new private function `_deactivate_gutenberg_when_incompatible_with_wp()` introduced in [52165].

Avoid a fatal error due to `WP_Theme_JSON_Schema` and potentially other classes and/or functions redeclarations when updating to WordPress 5.9 with an incompatible version of the Gutenberg plugin.
This commit uses the same strategy from 5.8. Moves the plugin deactivation code (introduced in [51266]) to a private function for reuse in 5.8, 5.9, and future major releases.

This adds a one-off notice to the dashboard in the event WordPress has automatically deactivated a plugin due to incompatibility with the new version of WordPress.
Introduces the new private function `deactivated_plugins_notice()` to display the notice in the dashboard. Introduces the new auto-loaded option `wp_force_deactivated_plugins` to store a list of automatically deactivated plugins; the option is used on both a site and network level.

When files are copied into place, check whether opcode invalidation is available and attempt to invalidate to avoid unintended behavior or fatal errors from themes, plugins, or core.
Introduces `wp_opcache_invalidate()` to allow safe invalidation of PHP files from opcode cache, and a filter, `wp_opcache_invalidate_file` to override the behavior.
Replaces the existing calls to `opcache_invalidate()` in the plugin and theme editors to use the new function.
Thanks to jnylen0 for porting over a patch from ClassicPress that provided much of the approach for what is being committed.

In WordPress 3.2 support for IE6 was dropped, IE7 followed a few versions later. With the 4.8 release, WordPress officially ended support for Internet Explorer versions 8, 9, and 10. Yet, we still have shipped CSS for the unsupported IE versions....until now! Goodbye to ie.css and star hacks!
* Removes ie.css and `ie` style handle.
* Removes IE specific class names and any related CSS.
* Drops support for IE8 and older in `wp_customize_support_script()`.
* Updates compatibility mode for CSS minification to `ie11`.

This avoids the performance overhead of the function call every time `dirname( __FILE__ )` was used instead of `__DIR__`.
This commit also includes:
* Removing unnecessary parentheses from `include`/`require` statements. These are language constructs, not function calls.
* Replacing `include` statements for several files with `require_once`, for consistency:
* `wp-admin/admin-header.php`
* `wp-admin/admin-footer.php`
* `wp-includes/version.php`
