Delete SkBitmapRegionCanvas

This was an approach we considered for implementing Android's
BitmapRegionDecoder.

It was useful for testing and comparison, but now is no longer worth
maintaining and testing.

The approach to subset/scaled decodes (clipped decode, then scale)
may be worth reconsidering at some point.
