This changeset modifies the Site Health panel for HTTPS to provide more accurate recommendations based on whether the environment is already set up for HTTPS.
* Introduces `wp_is_using_https()` to check whether the site is configured to use HTTPS (via its Site Address and WordPress Address).
* Introduces `wp_is_https_supported()` to check whether the environment supports HTTPS. This relies on a cron job which periodically checks support using a loopback request.

In [49162], GitHub Action workflow configuration files were introduced to run all of Core’s automated testing with the intent to fully transition after some time was allowed for testing.
After two full months of testing, the time to finish this transition has come.
We thank TravisCI for testing the codebase through nearly 20 major and many more minor releases.

The `twenty-twenty-one-ie11-polyfills` script now has a `null` source, and the new `twenty-twenty-one-ie11-polyfills-asset` (which points to the actual `polyfills.js` source) will be loaded only if IE is detected by through the use of `wp_get_script_polyfill()`.
Because the original script name remains the same, this change is backwards compatible with any code registering `twenty-twenty-one-id11-polyfills` as a script dependency.

While `loading=“eager”` is a supported alternative to omitting the attribute entirely, browsers follow the value of this attribute explicitly when specified.
Specifying `eager` would prevent the user from receiving any additional potential benefits implemented at the browser level, such as further mechanisms to automatically decide which elements to lazy-load.

Related Gutenberg PR: https://github.com/WordPress/gutenberg/pull/25220.
It aligns with the latest changes added by aristath to the Gutenberg project. As part of styles splitting for core blocks, there was a special pattern introduced for how style handles are named. Ideally, we would apply it to all blocks but there might be some backward compatibility considerations so I left the handling for non-core blocks unchanged.
Props aristath.

In addition to MySQL, WordPress also supports MariaDB for databases. This makes changes to the local Docker environment to allow MariaDB to be used instead, if desired.
The `LOCAL_DB_TYPE` environment variable will now be used to determine which type of database container to use. This will default to `mysql`, but will also accept `mariadb`.
The `LOCAL_MYSQL` environment variable (which previously held the version of MySQL to use) has been replaced with the new, more generic `LOCAL_DB_VERSION` environment variable.
This change will make it possible to perform automated testing on a wider array of supported database types and versions.

This introduces a new GitHub Action workflow to generate a code coverage report when running the PHPUnit test suite as both a single and multisite install.
The workflow will run once per week on Sunday at 00:00 UTC.
For now, the reports are not submitted anywhere, but they will be uploaded to the workflow run as ZIP file artifacts where they will persist for 90 days.
Making code coverage reports more readily available will hopefully better highlight areas of Core with poor coverage, and encourage more contributors to help increase test coverage of those areas.

Previously, `1.0.0` was used for the version. This is inconsistent with the versioning used in the other default themes, which use use X.X and not X.X.X.
This change corrects all `1.0.0` occurrences to `1.0`, and adds the additional context of `Twenty Twenty-One` to avoid confusion with `WordPress 1.0`.

* Expands the capabilities of `wp_filter_content_tags()` to add the attribute to iframe tags if enabled.
* Modifies the default behavior of `wp_lazy_loading_enabled()` so that it returns `true` for `iframe` tags.
* Introduces a `wp_iframe_tag_add_loading_attr()` function.
* Introduces a `wp_iframe_tag_add_loading_attr` filter.
Like for images, the attribute is only added to iframes which have both `width` and `height` specified (see related #50367).
