hwc: rgz: Introduce scaling support
Adds scaling support to the regionizer code.
Limitations:
+ When blending two layers with scaling two blits are issued
instead of one. This is due to a Bltsville API limitation
which prevents specifying two different scale modes for each
source.
+ Support for scaling and rotation on the same blit is not
possible yet due to a GC driver bug.
