This changeset implements the refined lazy-loading behavior outlined in https://make.wordpress.org/core/2021/07/15/refining-wordpress-cores-lazy-loading-implementation/ in order to improve the Largest Contentful Paint metric, which can see a regression from images or iframes above the fold being lazy-loaded. Adjusting this so far has been possible for developers via filters and still is, however this enhancement brings a more accurate behavior out of the box for the majority of themes.
Specifically, this changeset skips the very first "content image or iframe" on the page from being lazy-loaded. "Content image or iframe" denotes any image or iframe that is found within content of any post in the current main query loop as well as any featured image of such a post. This applies both to "singular" as well as "archive" content: On a "singular" page the first image/iframe of the post is not lazy-loaded, while on an "archive" page the first image/iframe of the _first_ post in the query is not lazy-loaded.
This approach refines the lazy-loading behavior correctly for the majority of themes, which use a single-column layout for post content. For themes with multi-column layouts, a new `wp_omit_loading_attr_threshold` filter can be used to change how many of the first images/iframes are being skipped from lazy-loaded (default is `1`). For example, a theme using a three-column grid of latest posts for archives could use the filter to override the threshold to `3` on archive pages, so that the first three content images/iframes would not be lazy-loaded.

Introduces a new function called `wp_list_users()`. Similar to other list functions such as `wp_list_authors()`, it lists all the users of the site. Options are available to configure the HTML output.
Following the same pattern of the other list functions, the list's HTML output is rendered by default. Setting the `echo` argument to `false`, returns the list's HTML output.
A new test class is included.

These checks were added in [51193] and [51197] as a temporary measure to prevent a site owner from activating a Full Site Editing theme when Gutenberg plugin was not active.
Because Core only had partial support for the features required for FSE, the front end of the site would display a white screen or error message to visitors. Unless the site owner visited the front end, there would be no indication that there was a problem.
Since 5.9 will include the remaining features required for FSE, these checks can be removed.

Introduces a new filter 'is_post_status_viewable' which allows overriding the check.
The function's return signature is a boolean type. This commit ensures
the return signature remains unchanged by requirinng a strict boolean
type of the returned filtered value.
Why?
* To maintain this signature and backwards-compatibility.
* To future prepare for PHP 8.1 and beyond.
An explanation is included in the filter's DocBlock.

As a legacy from the old Health Check plugin, the constant `WP_LOCAL_DEV` was included in the debug data under the "WordPress Constants" section. This was incorrect, and has never been a constant used by core.
Instead, that field is now replaced by `WP_ENVIRONMENT_TYPE`, which was introduced with WordPress 5.5, and is a much more appropriate value to provide in a debug scenario.

The `get_core_checksums()` and `wp_version_check()` functions call the PHP native `http_build_query()` function, the second parameter of which is the ''optional'' `$numeric_prefix` parameter which expects a non-nullable `string`.
A parameter being optional, however, does not automatically make it nullable.
As of PHP 8.1, passing `null` to a non-nullable PHP native function will generate a deprecation notice.
In this case, this function call yielded a `http_build_query(): Passing null to parameter #2 ($numeric_prefix) of type string is deprecated` notice.
Changing the `null` to an empty string fixes this without a backward compatibility break.

The icon used to be a rather blocky checkmark, but has now been changed to the more friendly, and less ambiguous, smiley dashicon.
It also helps cover a rare cases where a checkmark, while often used to mark something as done, may also be used to indicate that something is incorrect (many thanks to my 6th grade teacher for this rationale).
As an added bonus, this commit also adjusts the margins used around the icon, to make it fit more nicely on both large and small viewports.

By default, only users with the `edit_theme_options` capability can access the sidebars and widgets REST API endpoints. In this commit, A new `show_in_rest` parameter is added to the `register_sidebar` function. When enabled, all users will be able to access that sidebar and any widgets belonging to that sidebar.
This commit reduces the `context` for a widget's `instance` information to only `edit`. This is to ensure that internal widget data is not inadvertently exposed to the public. A future ticket may expose additional APIs to allow widget authors to indicate that their instance data can be safely exposed. REST API consumers intending to access this `instance` information should take care to explicitly set the `context` parameter to `edit`.
