Meta: Remove object subtype handling from `register_meta()`. 

Registration is now based solely on object type, which allows the code around this to be simplified significantly.

In the process of making this adjustment:

* `register_meta()`, `unregister_meta_key()`, `get_registered_metadata()`, and `registered_meta_key_exists()` no longer return `WP_Error` objects.
* The recently introduced `wp_object_type_exists()` function and the restriction on object type has been removed.

Note: No guarantee of uniqueness is made across object subtypes. Registered meta keys should be uniquely prefixed to avoid conflict.

Fixes #35658.
