REST API: Expose all themes in the themes controller.

Browse Source 
Previously, only the active theme was made available. This commit allows for all themes to be queried if the user has the `switch_themes` or `manage_network_themes` capabilities.

This commit also no longer exposes the `page`, `per_page`, `search` and `context` query parameters since they are not supported by this controller.

Props spacedmonkey, lpawlik, TimothyBlynJacobs.
Fixes #50152.
