freedreno: Drop fd_context_lock() and friends

These were actually just wrappers for the screen->lock, left over from
moving things around a long time ago.  Lets drop them to make things
more explicit (that we are locking the screen, not the context).

Involves a bit of shuffling things around to untangle header deps, but
no functional change.
