Theme Translations: Allow for theme pomo files to be loaded from WP_LANG_DIR/themes/{$domain}-{$locale}.(p|m)o.
This directory format is what we have chosen for Language Packs (See #18200), but which is currently delayed.

By making this change, we can ship localised theme files within core for bundled themes, and avoid the issues associated with Theme Updates overwriting/removing the language files.

Fixes #18960

* Introduces a filter: exit_on_http_head (we send TRUE through it)
