Since PHP 8.1, `readonly` is a reserved keyword and cannot be used as a function name.
In order to avoid PHP parser errors, the `readonly()` function was extracted to a separate file and is now only included conditionally on PHP < 8.1.
This commit also:
* Moves the tests for the `__checked_selected_helper()` function and all the related functions to their own file.
* Switches to named data providers. This makes the output when using the `--testdox` option more descriptive and is helpful when trying to debug which data set from a data provider failed the test.
* Improves the tests in question to make them feature-complete and expand test coverage.

In `wp_get_document_title(), the returned value is currently passed directly through `wptexturize()`, `convert_chars()`, and `capital_P_dangit()`, and is done so after the `document_title_parts` filter is run.
This makes it impossible to fully control the output of `wp_get_document_title()` and is inconsistent with how other similar text is processed with these functions.
This commit introduces the `document_title` filter, which is run immediately before returning the results of the `wp_get_document_title()` function and moves the three formatting functions mentioned above to the new filter hook. This allows developers to further modify the title after being prepared by WordPress, or to modify the functions hooked to this filter as they wish.

This is part of a larger project in cleaning up core's admin CSS. This collapses all colors used in the CSS to one of 12 blues, greens, reds, and yellows, 13 grays, pure black, and pure white. The colors are perceptually uniform from light to dark, half of each range has a 4.5 or higher contrast against white, the other half has a 4.5 or higher contrast against black.
Standardizing on this set of colors will help contributors make consistent, accessible design decisions. The full color palette can be seen here: https://codepen.io/ryelle/full/WNGVEjw

This changeset introduces a filter-based Robots API, providing central control over the `robots` meta tag.
* Introduces `wp_robots()` function which should be called anywhere a `robots` meta tag should be included.
* Introduces `wp_robots` filter which allows adding or modifying directives for the `robots` meta tag. The `wp_robots()` function is entirely filter-based, i.e. if no filter is added to `wp_robots`, no directives will be present, and therefore the entire `robots` meta tag will be omitted.
* Introduces the following `wp_robots` filter functions which replace similar existing functions that were manually rendering a `robots` meta tag:
* `wp_robots_noindex()` replaces `noindex()`, which has been deprecated.
* `wp_robots_no_robots()` replaces `wp_no_robots()`, which has been deprecated.
* `wp_robots_sensitive_page()` replaces `wp_sensitive_page_meta()`, which has been deprecated. Its rendering of the `referrer` meta tag has been moved to another new function `wp_strict_cross_origin_referrer()`.
Migration to the new functions is straightforward. For example, a call to `add_action( 'wp_head', 'wp_no_robots' )` should be replaced with `add_filter( 'wp_robots', 'wp_robots_no_robots' )`.
Plugins and themes that render their own `robots` meta tags are encouraged to switch to rely on the `wp_robots` filter in order to use the central management layer now provided by WordPress core.

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.

In `get_the_archive_title()` split the internal `$title` variable into `$title` and `$prefix`. By using the new `get_the_archive_title_prefix` filter the prefix can now wrapped with custom elements or removed completely by using
{{{
add_filter( 'get_the_archive_title_prefix', '__return_empty_string' );
}}}
Also, wrap the title part with a `span` element and pass the original title and prefix to the existing `get_the_archive_title` filter, allowing further customization to the archive titles.

After [48039] it became clear that the non-linked custom logo on the home page needs an empty alt attribute, as in most of the cases the logo is decorative and doesn't need its purpose to be described.
This change outputs an empty alt attribute by default for the custom logo on the home page. If necessary, it is possible to use the new 'get_custom_logo_image_attributes' filter to manipulate the default attributes for the logo image and set an alt attribute.
