Update SkCanvas' experimental SkiaRenderer API

This lifts the temporary functions in SkGpuDevice into SkCanvas and
deprecates the older experimental_DrawImageSetV1 and
experimental_DrawEdgeAARect.  The new functions can handle paints and
transform batching. Internally, SkCanvas routes the old functions to the
new entry points and all device-level code is updated to handle the new
API features.

While touching all of the canvas/device/recording areas, the
experimental functions are grouped in an "EdgeAA" cluster instead of being
separated into the image category and the rectangle category.
