libhwc2.1: ensure displaycolor get correct lhbm state

setLhbmState call will trigger display validation (by calling
SF refresh). But the call could happen during a presentDisplay call.

The lhbm request will go with current presentDisplay but displaycolor
Update is not called, the LHBM compensation is skipped.

We don't want to delay the setLhbmState to next frame if not necessary.
So we need to move lhbm related scene update to UpdatePresent.

And setLhbmState call should not happpen between Lhbm scene update
and lhbm adjusted dbv query. Re-use current brightness mutex for protection.
If setLhbmState happens after prepareFrameCommit call, it has
to wait for next frame.
