Plumb SkMatrixProvider throughout Ganesh

Renames the provider to SkMatrixProvider, which is now also able to
provide the local-to-device matrix. Everywhere that does paint
conversion and FP generation now has access to the entire matrix
provider, instead of just the CTM.

This will allow the SkSL FP (and others) to fetch other matrix state.
