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.

[52232] relocated the Theme Editor menu item from Appearance to Tools for block themes. This commit relocates the Plugin Editor menu item from Plugins to Tools for block themes for a consistent workflow.
Both the Theme Editor and Plugin Editor menu items are renamed to "Theme File Editor" and "Plugin File Editor" respectively. Why? To better identify their purpose, i.e. to directly edit the code in the theme or plugin files. The rename is not limited to only block themes.

Revert the rollback features introduced for theme and plugin upgrades during the WordPress 5.9 cycle. A bug (suspected to be in third party virtualisation software) causes the upgrades to fail consistently on some set ups. The revert is to allow contributors further time to investigate mitigation options.

* Check for direct PHP flle access and only use `rename()` if true.
* Check whether the destination directory was successfully created.
* Clear the working directory so there is internal parity within the function between the results of a successful `rename()` and a fallback to `copy_dir()`.
* Use `move_dir()` in `WP_Upgrader::move_to_temp_backup_dir()` and `::restore_temp_backup()`.

Previously, when uploading a media item type that is not supported, the default error message claims that the reason it cannot upload is due to security reasons. This is not always true. Now the warning says that the type is not allowed, which is always true.

This change allows for external clients to supply a suggested filename via a `Content-Disposition` response header. This filename is processed through `sanitize_file_name()` to ensure it is allowable (on the server, MIME's, etc...) and `validate_file()` to prevent directory traversal.
If the suggested filename fails the above processing/checks, that suggestion is discarded and the standard temporary filename (generated by WordPress) is used.
If no `Content-Disposition` header is found in the response headers, the standard temporary filename continues to be used as per normal.
Included in this change are 6 additional PHPUnit tests with 9 assertions. These tests confirm that valid filename values are correctly saved, and invalid filename values are correctly rejected.

This replaces the `copy_dir()` usage in `WP_Upgrader::install_package()` and aims to avoid PHP timeout issues when installing or updating large plugins on slower systems like Vagrant or the WP Docker test environment.
The new function attempts a native PHP `rename()` function first and falls back to the previous `copy_dir()`.

As per the PHP manual:
> If the `component` parameter is omitted, an associative array is returned.
> If the `component` parameter is specified, `parse_url()` returns a string (or an int, in the case of `PHP_URL_PORT`) instead of an array. If the requested component doesn't exist within the given URL, `null` will be returned.
Reference: [https://www.php.net/manual/en/function.parse-url.php#refsect1-function.parse-url-returnvalues PHP Manual: parse_url(): Return Values]
This commit adds three unit tests for `download_url()`:
* The first test is "girl-scouting" to make sure that the code up to the point where the error is expected is tested.
* The second test exposed a PHP 8.1 `basename(): Passing null to parameter #1 ($path) of type string is deprecated` error due to the call to `parse_url()` returning `null` when the component requested does not exist in the passed URL.
* The output of the call to `parse_url()` stored in the `$url_path` variable is used in more places in the function logic. The third test exposes a second PHP 8.1 deprecation notice, this time for `substr(): Passing null to parameter #1 ($string) of type string is deprecated`.
This commit also removes duplicate `parse_url()` calls. Neither `$url` nor `$url_filename` are changed between when they are first received/defined and when they are re-used, so there is no need to repeat the function calls.

Instead of one cache entry for all upload folders for a site on multisite, this now caches for each folder and invalidates that cache based on context. In multisite, this should speed up `get_dirsize` calls since older directories that are much less likely to change will no longer have the size recalculated.

Using the canonical function name for PHP functions is strongly recommended, as aliases may be deprecated or removed without (much) warning.
This replaces all uses of the following:
* `join()` with `implode()`
* `sizeof()` with `count()`
* `is_writeable()` with `is_writable()`
* `doubleval()` with a `(float)` cast
In part, this is a follow-up to #47746.

The filter is the callback function added with `add_filter()`, therefore the hook passes a value to the filter, and the filter returns a value to change its behaviour.
The documentation is referring to the latter.

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.

For a number of years, most of the WordPress error messages have been prefixed with "Error:". However, these messages appear in a context where it's already clear an error occurred. Whether it's an error, a warning, or any other classification, that's not so relevant for users. The content of the message is the relevant part. The "Error:" prefix doesn't add great value while it does add unnecessary complexity for the message readability.
Also, revises some of these messages to improve clarity and removes HTML from translatable strings.
