SkRecord strawman

Record performance as measured by bench_record (out/Release/bench_record --skr) improves by at least 1.9x, at most 6.7x, arithmetic mean 2.6x, geometric mean 3.0x.  So, good.

Correctness as measured by DM (out/Debug/dm --skr) is ~ok.  One GM (shadertext2) fails because we're assuming all paint effects are immutable, but SkShaders are still mutable.

To do after this CL:
  - measure playback speed
  - catch up feature-wise to SkPicture
  - match today's playback speed
