Revert "use SkM44 internally"

This reverts commit 295cdf8775791abdcdcc9e098d31f3e40780c805.

Reason for revert: wacky gm colors, must have busted colormatrixfilter

Original change's description:
> use SkM44 internally
> 
> Today we use SkM44 in canvas, and SkMatrix44 in sksl (and colormatrix).
> This CL tries to move core to use a single type.
> 
> SkMatrix44 has callers in android and chrome, is loaded with double/float
> variants in its API. I am suggesting moving to a private, clean-start,
> API for internal use. SkM44 is much faster, and has a leaner API.
> 
> If eventually we can migrate clients to a shared impl/api, great. For now,
> I want to have one we are free to optimize/use as we see fit without
> worrying about changing client results.
