Peter Wilson 6219eb95bf Sitemaps: Prevent invalid provider names throwing errors. 
Validate the requested sitemap is a string before attempting to use it in a provider. This prevents `WP_Sitemaps_Registry::get_provider()` from triggering a fatal error in more recent versions of PHP.

The errors can be triggered by items outside the site owner or developers control (such as a user visiting `?sitemap[foo]=bar`) so the code fails silently to avoid filling error logs with unfixable errors.

Props costdev, dd32.
Fixes #56336.

Pascal Birchler 1f153b0d12 Sitemaps: Replace `wp_sitemaps_register_providers` filter with more suitable `wp_sitemaps_add_provider` filter. 
The previous filter failed the goal of allowing developers to filter all providers before they are registered, since it only filtered the built-in ones.

The more specific `wp_sitemaps_add_provider` filter enables exactly that, as it filters every sitemap provider right before it is added to the sitemaps registry.

Following [48536], rename the function to match the rest of the sitemaps logic.

Also eliminates some dead code after [48523].

Sergey Biryukov 12daeec1f7 Sitemaps: Rename 'sitemap' to 'provider' in `WP_Sitemaps_Registry` class.

Pascal Birchler 1f27914191 Sitemaps: Correctly enforce maximum number of sitemaps in index. 
Before this change, the limit of 50k entries was enforced for the number of providers, not the amount of sitemaps all providers add to the index in total.

Pascal Birchler 609dd1d14f Sitemaps: Add XML sitemaps functionality to WordPress. 
While web crawlers are able to discover pages from links within the site and from other sites, XML sitemaps supplement this approach by allowing crawlers to quickly and comprehensively identify all URLs included in the sitemap and learn other signals about those URLs using the associated metadata.

See https://make.wordpress.org/core/2020/06/10/merge-announcement-extensible-core-sitemaps/ for more details.

This feature exposes the sitemap index via `/wp-sitemap.xml` and exposes a variety of new filters and hooks for developers to modify the behavior. Users can disable sitemaps completely by turning off search engine visibility in WordPress admin.

This change also introduces a new `esc_xml()` function to escape strings for output in XML, as well as XML support to `wp_kses_normalize_entities()`.
