Synchronize surface transaction 

Until now the SurfaceControl transaction was being applied
asynchronously, which could lead to it being executed out of sync with
launcher drawing.
This became an issue at higher refresh rates, where frames are produced
at a much faster pace.

In order to fix this issue, we can use BLAST transactions, which are
annotated with a frame number.

Test: record video, go through it manually
