Brian Osman 268ed57d71 Revert "Extend SkCanvas matrix stack to be 4x4, but with (basically) the same public API." 
This reverts commit 98bfcc7ff3.

Reason for revert: Flutter hitting assert:
../../third_party/skia/src/core/SkCanvas.cpp:1432: fatal error: "assert(fIsScaleTranslate == fMCRec->fMatrix.isScaleTranslate())"

Original change's description:
> Extend SkCanvas matrix stack to be 4x4, but with (basically) the same public API.
> 
> Devices receive the 4x4, but by default they simply downsample it to SkMatrix.
> 
> New SkM44 matrix for the impl. It differs from SkMatrix44 in a few ways
> - no tracking of "type"
> - faster for concat, as it does not use doubles for intermediates
> - much simpler API
> 
> There are some low-bit differences in some gms, so adding a flag for clients to
> stage this change. (due to faster but lower-precision in SkM44::concat)
> 
> Performance: running canvas_matrix bench
> 
> 3x3 version:

>     113.47  	canvas_matrix_trans	8888
> 
> Why faster?
> - not tracking matrix_type helps a lot it seems
> - faster full concat (no doubles)
