Remove antialiasing control from GrPaint.

This adds an additional param (of new enum type GrAA) to draws that can antialias and a new enum GrAAType to indicate the AA technique (none, fragment shader computed coverage, msaa).

Some GMs change due to this:
1) In some places we weren't disabling MSAA when the draw was supposed to be unantialiased.
2) Some bounding rect draws that use GrFragmentProcessors were unnecessarily turning on antialiasing, by disabling it a very small number of pixel LSBs change.
