Add setMatrix with SkM44 as an argument

This is step one of a multistep process to move the paint_op_buffer from
SkMatrix->SkM44. The steps are
1. Add setMatrix(SkM44) <- this step
2. Add concat(SkM44)
2a. Add helper functions to SkM44 to allow it to do stuff like this:
  https://source.chromium.org/chromium/chromium/src/+/master:cc/paint/display_item_list.cc;l=412?q=display_item_list&sq=package:chromium&ct=os
3. Change setMatrix(SkMatrix) to use the SkM44 function
4. Change concat(SkMatrix) to use the SkM44 function
5. Remove the early-outs for checking identity in the ::Serialize
functions and see if they have perf impact.

SkCanvas now supports this
https://skia-review.googlesource.com/c/skia/+/338596

It's necessary for perspective transforms
https://bugs.chromium.org/p/chromium/issues/detail?id=1140535

It needs to be serializable due to the record paint canvas.
