Two changes:
1. Remove special premul handling from gamut xform code
Alpha is a constant, so the gamut transformation results remain unchanged
(it distributes across the linear matrix multiply).
2. Use SkMatrix44 rather than array of floats
Preserves semantic intention, and makes upcoming code (where we transform
colors on the CPU by that matrix) simpler.
