Themes: Improve document title output.

Browse Source 
Introduces more flexibility in filtering all parts of the document title,the
separator, and a way to short-circuit title generation. Plugins can now also
check for theme support and reliably filter the entire output. See #18548.
Deprecates `wp_title()`.

Fixes #31078.
