6bdbf4412b Improve naive SkColorXform to half floats 
This should give us a good baseline to explore using SkRasterPipeline.

A particular colorxform to half float drops from 425us to 282us on my desktop.

Color Xform to Half Float (HP z620)
Original                              425us
Trans16 (not 32)                      355us
Vector Trans16                        378us
Trans16 + Keep Halfs in Vector        335us
Vector Trans16 + Keep Halfs in Vector 282us
Final                                 282us

Color Xform to Half Float (Nexus 5X)
Original                              556us
Final                                 472us

2cee902847 Add color correction benchmark - with comparison to qcms 
--colorImages is empty by default so this won't affect the runtime of
the bots.  To run locally, use --colorImages <path> and
--benchType skcolorcodec.

Two takeaways so far:
Color correction is (currently) slower than jpeg decodes.
Our reference solution is slower than qcms.
