Brian Osman 3695bdb587 Refactor SkMatrixProvider slightly 
There was only one virtual method, so switch that to a bool stored in
the base class. The derived types exist as hints for the reader, and an
easy way to adjust how the new localToDevice is constructed.

With this change, we don't need SkSimpleMatrixProvider. SkMatrixProvider
is concrete, so we can use it directly. SkOverrideDeviceMatrixProvider
no longer needs the original provider for anything, so remove that
parameter. It now exists solely to inhibit the hitsPixelCenters flag.

Fix a few spots (SkParticleBinding, some sites in SkRuntimeEffect) where
we used SkSimpleMatrixProvider, even though the local coordinates being
passed did not obey the hits-pixel-centers constraints.

Most importantly, document how localToDeviceHitsPixelCenters works.
