This adds support for debug.hwui.profile and
debug.hwui.show_dirty_regions to the Skia pipelines.
There still may be some follow up work for profiling
with visual bars. The speed at which the renderer
is able to draw the rects in the graph is having a
noticeable effect on the actual data in the graphs.
Test: Verified that the features work as expected.
