Themes: Fix caching issue in get_post_templates method in WP_Theme.

Fix an edge case caching issue, where if a developer use the  `wp_cache_themes_persistently` filter and is running the site in multisite configuration, it meant block template are incorrectly cached. Block templates are stored in the posts table. But in a multisite configuration, different sites on the multisite could have different block templates stored in there post table. As themes cache group is a global group, it resulted in incorrect values being cached.

Fixes #57886.
