Adds small pictures for drawRect(), drawTextBlob(), and drawPath().
These cover about 89% of draw calls from Blink SKPs,
and about 25% of draw calls from our GMs.
SkPicture handles:
- serialization and deserialization
- unique IDs
Everything else is left to the subclasses:
- playback(), cullRect()
- hasBitmap(), hasText(), suitableForGPU(), etc.
- LayerInfo / AccelData if applicable.
The time to record a 1-op picture improves a good chunk
(2 mallocs to 1), and the time to record a 0-op picture
greatly improves (2 mallocs to none):
picture_overhead_draw: 450ns -> 350ns
picture_overhead_nodraw: 300ns -> 90ns
