Add new API to check whether a Bitmap was modified.

Bitmap.getGenerationId() can be used by caches to find out if a Bitmap has been
modified. This simply exposes an existing Skia API.

This change also adds a small test app for Canvas hardware acceleration. The new
Bitmap API is required to implement a texture cache.
