block: Remove bdrv_(set_)enable_write_cache()
The only remaining users were block jobs (mirror and backup) which unconditionally enabled WCE on the BlockBackend of the target image. As these block jobs don't go through BlockBackend for their I/O requests, they aren't affected by this setting anyway but always get a writeback mode, so that call can be removed.
