Felix Arntz c81db1f6e6 Security, Site Health: Detect HTTPS support and encourage switching.
This changeset modifies the Site Health panel for HTTPS to provide more accurate recommendations based on whether the environment is already set up for HTTPS.

* Introduces `wp_is_using_https()` to check whether the site is configured to use HTTPS (via its Site Address and WordPress Address).
* Introduces `wp_is_https_supported()` to check whether the environment supports HTTPS. This relies on a cron job which periodically checks support using a loopback request.

TimothyBlynJacobs 2df94804d4 Site Health, App Passwords: Test if the Authorization header is populated correctly.
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 tests if the header is being filled with the expected values. For Apache users, we direct the user to visit the Permalinks settings to flush their permalinks. For all other users, we direct them to a help document on developer.wordpress.org.

* In HTTPS tests, instead of a hardcoded check for `localhost`.
* In `WP_DEBUG` and `WP_DEBUG_DISPLAY` tests, to set the status to `recommended` instead of `critical`.

desrosj 8778aa8922 Site Health: Improve the reliability of asynchronous tests.
This change adds additional logic to catch HTTP failures that do not return a `WP_Error` object (for example, a wp-json REST API error error).

This also fixes instances where REST API callbacks performed from cron do not work due to a lack of authentication by introducing a direct callback route that asynchronous tests can register.

Sergey Biryukov 651f426b3a General: Remove `noreferrer` from `wp_targeted_link_rel()` and other uses.
When `noopener noreferrer` was originally added in #37941 and related tickets, the `noreferrer` bit was specifically included due to Firefox not supporting `noopener` at the time.

Since `noopener` has been supported by all major browsers for a while, it should now be safe to remove the `noreferrer` attribute from core.

Sergey Biryukov 0e3147c40e Coding Standards: Replace alias PHP functions with the canonical names.
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

TimothyBlynJacobs 039ce3f16f Site Health, REST API: Move async tests to REST API endpoints.
This provides more flexibility when writing tests and benefits from running in a front-end context which is necessary for some tests like checking that updates are supported. Additionally, this provides a more robust interface for developers who want to integrate with Site Health tests.

Because the `wp/v2` endpoint is reserved for modeling core entities, site health is registered in its own `wp-site-health/v1` namespace.

The existing ajax actions have been maintained for backward compatibility.

desrosj 4b60af1a6a General: Remove “whitelist” and “blacklist” in favor of more clear and inclusive language.
“The WordPress open source community cares about diversity. We strive to maintain a welcoming environment where everyone can feel included.”

With this commit, all occurrences of “whitelist” and “blacklist” (with the single exception of the `$new_whitelist_options` global variable) are removed. A new ticket has been opened to explore renaming the `$new_whitelist_options` variable (#50434).

Changing to more specific names or rewording sentences containing these terms not only makes the code more inclusive, but also helps provide clarity. These terms are often ambiguous. What is being blocked or allowed is not always immediately clear. This can make it more difficult for non-native English speakers to read through the codebase.

Words matter. If one contributor feels more welcome because these terms are removed, this was worth the effort.

desrosj 447536a0e6 Site Health: Display the REST API test error codes correctly.
This change fixes an issue where the error codes associated with failed REST API tests are not being printed to the screen. In addition, the square brackets have been replaced with parentheses for consistency, and the error code (which is much less useful to end-users than the error message itself) has been moved to the end of the line.

This also clarifies the associated translator comments.

Props afercia, desrosj.
Fixes #49426.

Sergey Biryukov 47ed56f38f Code Modernization: Replace `dirname( __FILE__ )` calls with `__DIR__` magic constant.
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`

Sergey Biryukov acd0a3ca99 Site Health: Add a test for PHP default timezone.
The test reports a failure if the default timezone was changed with `date_default_timezone_set()` to anything other than `UTC`.

WordPress historically uses `UTC` as the default timezone for calculating date and time offsets, overriding it is not recommended and can cause widespread and obscure issues.
