Make SkDevice preserve SkCanvas' 4x4 matrix

For now, getting the 4x4 matrix is still opt-in, and the vast majority
of code will continue to use the 3x3 matrix. This does fix marked
matrices when the CTM includes any Z.

Most of these changes ensure that APIs used to save and restore the CTM
operate on the 4x4, so that we don't accidentally discard Z.
