* Add `customize_value_custom_css` filter to `WP_Customize_Custom_CSS::value()` method.
* Introduce `customize_update_custom_css_post_content_args` filter in `WP_Customize_Custom_CSS::update()` method.
* Make clear that `wp_get_custom_css()` and `wp_get_custom_css` filter are specifically for obtaining the value to render/display. Eliminate use of `wp_get_custom_css()` when getting the setting value. Use the underlying `post_value` directly when `is_previewed`.
* Move anonymous functions handing JS previewing for `custom_logo`, `custom_css`, and `background` into named functions on the `wp.customize.settingPreviewHandlers` to allow plugins to override/extend preview logic.
* Update `_custom_background_cb` to always print a `style` tag wen in the customizer preview, and update background preview logic to replace existing style element instead of appending a new style to the head so that background changes don't unexpectedly override any Custom CSS in the preview's stylesheet cascade.

"Header Visuals" is a bit vague since the title/tagline are arguably
also “header visuals”. "Header Media" is more descriptive and is
consistent with how we refer to images/videos throughout core.

Removes the `.customize-partial-edit-shortcut-left-margin` class which was not effective on some themes, created a worse experience for other themes, and which did not recalculate when the preview was reflowed or resized. Now some small-width media queries are added to handle common cases while more dramatic issues can be handled by the theme. Also renames `Partial.positionEditShortcut()`to `Partial.addEditShortcutToPlacement()` which is a more accurate description of its function.

Restoring the current user context when saving a setting ensures filters apply as expected, such as Kses. When a user is not associated with a given setting change, continue to override `capability` to be `exist` when saving. Skip overwriting setting values in a changeset that have not changed, facilitating concurrent editing and amending a changeset by a user with fewer privileges.

Additionally, use these meta-caps in the REST API endpoints.
Previously, register_meta()'s auth_callback had no effect for non-post meta. This introduces `{add,edit,delete}_{comment,term,user}_meta` meta-caps to match the existing post meta capabilities. These are currently only used in the REST API.

The CSS property `background-attachment: fixed` is disabled in some mobile browsers for performance reasons. So here, the fix increases the breakpoint where the `background-attachment: fixed` is applied to the front page images. Doing this removes the fixed backgrounds and the issue from all smaller screens, but the downside is that it also removes the fixed backgrounds from smaller laptops. It's also possible future devices could fall into this breakpoint, but this seems to be the most practical solution.

Previously there was no way to remove the user locale setting again, even though that might be desirable.
This adds a new 'Site Default' option to the user-specific language setting by introducing a new `show_site_locale_default` argument to `wp_dropdown_languages()`.

* 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.

Now all public query vars are not supoprted via `?filter` in the REST API, we can remove the get_allowed_query_vars() method and filter. To provide developers with a good altnerative to `filter`, the `"rest_{$this->post_type}_collection_params"` filter has been added.
