`str_contains()` was introduced in PHP 8.0 to perform a case-sensitive check indicating if the string to search in (haystack) contains the given substring (needle).
WordPress core includes a polyfill for `str_contains()` on PHP < 8.0 as of WordPress 5.9.
This commit replaces `false !== strpos( ... )` with `str_contains()` in core files, making the code more readable and consistent, as well as better aligned with modern development practices.
Follow-up to [52039], [52040], [52326], [55703], [55710], [55987].

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`

* Removes `aria-hidden` argument. Lets `aria-hidden="true"` be there by default and sets it empty when there is `title` and `desc`.
* Adds unique IDs for title and desc for accessible implementation options.
* Removes absolute path in the Customizer. It didn't work in Internet Explorer, and the original bug is fixed in #30028.
* Add whitespace around `<use>`, from #38387.
