Update wp_kses_bad_protocol() to recognize : on uri attributes,
wp_kses_bad_protocol() makes sure to validate that uri attributes don't contain invalid/or not allowed protocols. While this works fine in most cases, there's a risk that by using the colon html5 named entity, one is able to bypass this function.

The Site Health tool serves two purposes:
- Provide site owners with information to improve the performance, reliability, and security of their site.
- Collect comprehensive debug information about the site.
By encouraging site owners to maintain their site and adhere to modern best practices, we ultimately improve the software hygeine of both the WordPress ecosystem, and the open internet as a whole.

Prior to this change, querying sites early in the bootstrap process could potentially cause a fatal error, since at that stage the filter to bail on updating site meta cache if the respective database table has not been installed yet is not hooked in yet. This changeset forces the filter to be added if that is not already the case.

The `change` event was previously required to ensure that the Customizer picked detected changes to the widget's content and synced them to the preview. In the current state, though, the `trigger( 'change' )` is no longer required and is causing issues with the widget's “Done” and “Save” buttons.

A direct URL to where a user can update PHP for their website can now be specified in one of two ways:
- Defining the `WP_DIRECT_UPDATE_PHP_URL` environment variable.
- Returning a URL to the `wp_direct_php_update_url` filter.
When a URL is specified, an additional “Update PHP” button will be displayed at the bottom of the Core dashboard widget informing administrators that their site is running an outdated version of PHP (see [42832]).

Restores `public`, `archived`, `mature`, `spam`, `deleted`, `lang_id`, and `WPLANG` to the `$meta` data passed to `wpmu_new_blog`. This hook was deprecated in 5.1.0, but code using it still relies on this data.

The filter is only run if the wordpress.org API considers the PHP version acceptable. This ensures that other plugins or hosting providers can only make this check stricter, but not loosen it.
