Cleanup implementation of hardware layers.

The new implementation relies on OpenGLRenderer's existing layer
code instead of duplicating it. The new code is much cleaner, with
simpler and better APIs and allows tracking of drawn regions inside
layers. Region tracking is not yet enabled but this will be done
in a future CL.
