Gary Pendergast 2d76b94be8 Shortcodes: Add a `do_shortcode_tag` filter.
The addition of the `pre_do_shortcode_tag` in [38506] allows plugins to short-circuit the shortcode execution process, which is particularly helpful for caching expensive shortcodes.

The `do_shortcode_tag` is the corresponding part of that system - when a shortcode hasn't been executed previously, there needs to be a clean method of populating the cache.

Pascal Birchler 4a88d55054 I18N: Introduce a user-specific language setting.
By enabling the user to select their preferred locale when editing the profile, we allow for greater personalization of the WordPress admin and therefore a better user experience.

The back end will be displayed in the user's individual locale while the locale used on the front end equals the one set for the whole site. If the user didn't specify a locale, the site's locale will be used as a fallback. The new `locale` property of the `WP_User` class can be used to retrieve the user's locale setting.

John Blackbourn b84023ea33 Taxonomy: Introduce more fine grained capabilities for managing taxonomy terms.
This introduces the singular `edit_term`, `delete_term`, and `assign_term` meta capabilities for terms, and switches the base capability name for tags from `manage_categories` to `manage_post_tags` and the corresponding `edit_post_tags`, `delete_post_tags`, and `assign_post_tags`.

All of these capabilities ultimately map to `manage_categories` so by default there is no change in the behaviour of the capabilities for categories, tags, or custom taxonomies. The `map_meta_cap` filter and the `capabilities` argument when registering a taxonomy now allow for control over editing, deleting, and assigning individual terms, as well as a separation of capabilities for tags from those of categories.

Jeremy Felt 1e9f495a18 Multisite: Use `get_sites()` in `get_blogs_of_user()`.
Previously, we looped through all of the site IDs found via user meta and ran `get_blog_details()` for each site. Now, we can pass all of the site IDs at once to `get_sites()` and receive full `WP_Site` objects.

To avoid possible issues with return type, sites are still processed into a standard object that also has a `userblog_id` property attached. Nothing is changed for non-multisite configurations.

Fixes #37061.

Jeremy Felt 5c038aefb3 Multisite: Ensure a consistent `WP_Site` return from `get_site_by_path()`.
It is possible to short circuit `get_site_by_path()` using the `pre_get_site_by_path` filter. When this happens and a standard site object is provided, we can make sure it is upgraded to a proper `WP_Site` object before passing it on.

Boone Gorges cb68ce1fc4 Tests: Reset post-related globals after each test.
Globals like `$pages` were leaking between tests, resulting in various
bits of weirdness.

Globals will kill WordPress. Globals are killing WordPress.

Dominik Schilling 324748a854 Taxonomy: Use `WP_Term_Query` in `get_term_by()`.
`WP_Term_Query` already supports querying terms by 'slug', 'name', and 'term_taxonomy_id'. Its additional arguments allow us to generate nearly the same SQL queries as before.
This change has one yuge benefit: the term queries are now cached. 

Add tests to increase coverage of `get_term_by()`.
