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.

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.

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()`.

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`

The PHP native JSON extension has been bundled and compiled with PHP by default since version 5.2.0. Because the minimum version of PHP required by WordPress is now 5.6.20 (see #46594 and [45058]), the related polyfills and workarounds have been removed (see [46205-46206,46208]).
However, even though the JSON extension is now included in PHP by default, it is still possible to disable the extension in a custom configuration. This change will prevent sites from upgrading if the JSON extension is disabled to prevent compatibility issues.

* Add missing translator comments.
* Fix placement of some translator comments. Translator comments should be on the line directly above the line containing the translation function call for optimal compatibility with various `.pot` file generation tools. The CS auto-fixing, which changed some inconsistent function calls to multi-line function calls, is part of the reason why this was no longer the case for a select group of translator comments.
Includes minor code layout fixes.

Noteable changes:
- The `magic_quotes_runtime` and `magic_quotes_sybase` settings were removed in PHP 5.4, so no longer need to be set.
- Some functions that use external libraries can generate errors that can't be tested for, so are globally allowed to silence errors.
- Quite a few functions would cause errors if `safe_mode` was set. This setting was removed in PHP 5.4.
- Only a handful of `header()` calls needed corresponding `headers_sent()` checks for unit tests to pass, but more may need to be added as the nightlies builds are tested.
