Grouped backports for the 5.9 branch.
- XML-RPC: Switch to `wp_safe_remote()` when fetching a pingback URL. - HTML API: Prevent `WP_HTML_Tag_Processor` instances being unserialized and add some extra logic for validating pattern and template file paths. - KSES: Optimize PCRE pattern detecting numeric character references. - Customize: Improve escaping approach used for nav menu attributes. - Media: Ensure the attachment parent is accessible to the user before showing a link to it in the media manager. - Administration: Ensure client-side templates are only detected when they're correctly associated with a script tag. - Filesystem API: Don't attempt to extract invalid files from a zip when using the PclZip library. Merges [61879-61885,61887,61890,61913] to the 5.9 branch.
