freedreno: add gmem_lock

The gmem state is split out now, so it does not require synchronization.
But gmem rendering still accesses vsc state from the context.

TODO maybe there is a better way?  For gen's that don't do vsc resizing,
this is probably easier.. but for a6xx there isn't really a great
position for more fine grained locking.  Maybe it doesn't matter since
in practice the lock shouldn't be contended.
