This changeset adds support for the `fetchpriority` attribute, which is typically added to a single image in each HTML response with a value of "high". This enhances load time performance (also Largest Contentful Paint, or LCP) by telling the browser to prioritize this image for downloading even before the layout of the page has been computed. In lab tests, this has shown to improve LCP performance by ~10% on average.
Specifically, `fetchpriority="high"` is added to the first image that satisfies all of the following conditions:
* The image is not lazy-loaded, i.e. does not have `loading="lazy"`.
* The image does not already have a (conflicting) `fetchpriority` attribute.
* The size of of the image (i.e. width * height) is greater than 50,000 squarepixels.
While these heuristics are based on several field analyses, there will always be room for optimization. Sites can customize the squarepixel threshold using a new filter `wp_min_priority_img_pixels` which should return an integer for the value.
Since the logic for adding `fetchpriority="high"` is heavily intertwined with the logic for adding `loading="lazy"`, yet the features should work decoupled from each other, the majority of code changes in this changeset is refactoring of the existing lazy-loading logic to be reusable. For this purpose, a new function `wp_get_loading_optimization_attributes()` has been introduced which returns an associative array of performance-relevant attributes for a given HTML element. This function replaces `wp_get_loading_attr_default()`, which has been deprecated. As another result of that change, a new function `wp_img_tag_add_loading_optimization_attrs()` replaces the more specific `wp_img_tag_add_loading_attr()`, which has been deprecated as well.
See https://make.wordpress.org/core/2023/05/02/proposal-for-enhancing-lcp-image-performance-with-fetchpriority/ for the original proposal and additional context.

`str_starts_with()` and `str_ends_with()` were introduced in PHP 8.0 to perform a case-sensitive check indicating if the string to search in (haystack) begins or ends with the given substring (needle).
WordPress core includes a polyfill for these functions on PHP < 8.0 as of WordPress 5.9.
This commit uses `str_starts_with()` and `str_ends_with()` in core files where appropriate:
* `$needle === substr( $string, 0, $length )`, where `$length` is the length of `$needle`, is replaced with `str_starts_with( $haystack, $needle )`.
* `$needle === substr( $string, $offset )`, where `$offset` is negative and the absolute value of `$offset` is the length of `$needle`, is replaced with `str_ends_with( $haystack, $needle )`.
This aims to make the code more readable and consistent, as well as better aligned with modern development practices.

While `strpos()` is slightly faster than the polyfill on PHP < 8.0, `str_starts_with()` is noticeably faster on PHP 8.0+, as it is optimized to avoid unnecessarily searching along the whole haystack if it does not find the needle.

This new function makes it easier to switch to a specific user’s locale by reducing duplicate code and storing the user’s ID as additional context for plugins to consume. Existing usage of `switch_to_locale()` in core has been replaced with `switch_to_user_locale()` where appropriate.
Also, this change ensures `WP_Locale_Switcher` properly filters `determine_locale` so that anyyone using the `determine_locale()` function will get the correct locale information when switching is in effect.

As per the PHP manual:
> If the `component` parameter is omitted, an associative array is returned.
> If the `component` parameter is specified, `parse_url()` returns a string (or an int, in the case of `PHP_URL_PORT`) instead of an array. If the requested component doesn't exist within the given URL, `null` will be returned.
Reference: [https://www.php.net/manual/en/function.parse-url.php#refsect1-function.parse-url-returnvalues PHP Manual: parse_url(): Return Values]
In PHP 8.1, if the home URL does not have a "host" component, it would lead to a `substr(): Passing null to parameter #1 ($string) of type string is deprecated` notice.
Changing the logic around and adding validation for the return type value of `wp_parse_url()` prevents that.
