[canvaskit] Support getImageData/putImageData
setMatrix -> _setMatrix with the hope of removing it
from the API (it breaks the save()/restore() model) and
replacing it with concat (which I'll try in a follow on CL).
Adds MakeImage for those times when a client has pixels
and needs to clip them (e.g. putImageData with 7 args).
This removes SkSurface._readPixels, which I might have
been holding wrong. It might get re-surfaced eventually.
