SkiaRenderer is ignoring the flag |force_anti_aliasing_off_| in
RenderPassDrawQuad and SolidColorDrawQuad. Check for this flag and turn
off AA if it is present.

The pixel tests also expect alpha blending to be disabled if this flag
is present, so use blend mode kSrc instead of kSrcOver.

This fixes the tests RenderPassDrawQuadForceAntiAliasingOff and
SolidColorDrawQuadForceAntiAliasingOff for SkiaRenderer, so enable them.
Also enable TileDrawQuadForceAntiAliasingOff and SolidColorDrawQuad,
which are passing after other changes.
