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.

This aims to make the update process more reliable and ensures that if a plugin or theme update fails, the previous version can be safely restored.
* When updating a plugin or theme, the old version is moved to a temporary backup directory:
* `wp-content/upgrade/temp-backup/plugins/[plugin-slug]` for plugins
* `wp-content/upgrade/temp-backup/themes/[theme-slug]` for themes.
* If the update fails, then the temporary backup kept in the `upgrade/temp-backup` directory is restored to its original location.
* If the update succeeds, the temporary backup is deleted.
To further help troubleshoot plugin and theme updates, two new checks were added to the Site Health screen:
* A check to make sure that the `temp-backup` directory is writable.
* A check that there is enough disk space available to safely perform updates.
To avoid confusion: The `temp-backup` directory will NOT be used to "roll back" a plugin to a previous version after a completed update. This directory will simply contain a transient backup of the previous version of a plugin or theme being updated, and as soon as the update process finishes, the directory will be empty.

The test to confirm if Authorization headers can be used and recognized by WordPress needs to include a username and password combination that WordPress can compare against during the testing phase. The inclusion of credentials here would unfortunately also invalidate any existing basic auth session for the site, for example if the user had added this as an extra layer of security on their back-end.
This test is now skipped if the `wp_is_site_protected_by_basic_auth()` function detects that basic auth is being used, since the act of using basic auth to access the site confirms that this feature is working as expected in the first place.

The test checking if the REST API is available, includes a parameter for `context=edit` to make sure the block editor can function properly. This means a user session with editor capabilities is required for the test to pass, which is not the case during a scheduled event.

This implements a new filter, `site_health_navigation_tabs`, which takes an associated array of tab identifiers/slugs, and tab labels, allowing developers to add their own subpage to the Site Health interface as new tabs.
To output a custom page, or add to an existing page, the `site_health_tab_content` action is triggered whenever the `tab` query argument is present and not empty. This action includes the current tab as its argument, which a developer would match against to only output content when relevant.

See https://www.php.net/manual/en/ini.core.php#ini.post-max-size for details, as PHP 5.3.4 introduced this behavior for literal zero interpretation when the content type of a request is `application/x-www-form-urlencoded` or is not registered with PHP.

Switching a WordPress site from HTTP to HTTPS has historically been a tedious task. While on the surface the Site Address and WordPress Address have to be updated, existing content still remains using HTTP URLs where hard-coded in the database. Furthermore, updating _two_ URLs to migrate to HTTPS is still a fairly unintuitive step which is not clearly explained.
This changeset simplifies migration from HTTP to HTTPS and, where possible, makes it a one-click interaction.
* Automatically replace insecure versions of the Site Address (`home_url()`) with its HTTPS counterpart on the fly if the site has been migrated from HTTP to HTTPS. This is accomplished by introducing a `https_migration_required` option and enabling it when the `home_url()` is accordingly changed.
* A new `wp_replace_insecure_home_url()` function is hooked into various pieces of content to replace URLs accordingly.
* The migration only kicks in when the Site Address (`home_url()`) and WordPress Address (`site_url()`) match, which is the widely common case. Configurations where these differ are often maintained by more advanced users, where this migration routine would be less essential - something to potentially iterate on in the future though.
* The migration does not actually update content in the database. More savvy users that prefer to do that can prevent the migration logic from running by either deleting the `https_migration_required` option or using the new `wp_should_replace_insecure_home_url` filter.
* For fresh sites that do not have any content yet at the point of changing the URLs to HTTPS, the migration will also be skipped since it would not be relevant.
* Expose a primary action in the Site Health recommendation, if HTTPS is already supported by the environment, built on top of the HTTPS detection mechanism from [49904]. When clicked, the default behavior is to update `home_url()` and `site_url()` in one go to their HTTPS counterpart.
* A new `wp_update_urls_to_https()` function takes care of the update routine.
* A new `update_https` meta capability is introduced to control access.
* If the site's URLs are controlled by constants, this update is not automatically possible, so in these scenarios the user is informed about that in the HTTPS status check in Site Health.
* Allow hosting providers to modify the URLs linked to in the HTTPS status check in Site Health, similar to how that is possible for the URLs around updating the PHP version.
* A `WP_UPDATE_HTTPS_URL` environment variable or `wp_update_https_url` filter can be used to provide a custom URL with guidance about updating the site to use HTTPS.
* A `WP_DIRECT_UPDATE_HTTPS_URL` environment variable or `wp_direct_update_https_url` filter can be used to provide a custom URL for the primary CTA to update the site to use HTTPS.

* Correct the existing copy to indicate that both the Site Address and the WordPress Address need to be changed to fully switch to HTTPS.
* Link to the respective input fields via anchor links rather than to the overall General Settings screen.
* Show different copy if the site is using HTTPS for the WordPress Address (for example to have only the administration panel in HTTPS), but not for the Site Address.
* Inform the user about potential problems even when the site is already using HTTPS, for example if the SSL certificate was no longer valid.
* Always rely on fresh information for determining HTTPS support issues in Site Health, and therefore change the `https_status` test to become asynchronous.
* Rename the new private `wp_is_owned_html_output()` function to a more appropriate `wp_is_local_html_output()`.

In [49154] the async Site Health tests were changed to use the REST API instead of admin-ajax. An unintended side effect of this change was that the loopback tests which tried to ping the site's `admin_url()` were no longer authenticated because admin-cookies aren't provided to the REST API.
This commit adjusts the loopback test to use the front-end `site_url` which checks that cron will function properly. A follow-up ticket will focus on tests that will cover the file editor checks.

App Passwords rely on the Authorization header to transport the Basic Auth credentials. For Apache web servers, WordPress automatically includes a RewriteRule to populate the value for servers running in CGI or FastCGI that wouldn't ordinarily populate the value.

This change removes redundant CSS properties for different health check statuses in favor of utilizing the `.dashicons` class already in Core to define them more consistently. This also fixes the vertical alignment issues.

When viewing Site Health for a multisite install, there are a few recommendations that are not appropriate and could have negative implications for other sites on the install if the administrator follows the advice provided.
For example, Site Health recommends that inactive plugins and themes for a site should be removed. On a single site install, this is a great recommendation. However, on a multisite install, inactive plugins and themes for one site should not be removed because they could be active for other sites on the network.
This change also disables the `test_wp_version_check_attached()` test for multisite. This test checks for the presence of the `wp_version_check()` function on the `wp_version_check` hook, which is not present for every site on multisite.
