Update SkRandomScalerContext to handle mask filters.

SkRandomScalarContext would apply all path and mask filters twice, once
on the proxy and once to itself.

This also changes the SkScalerContext mask generation in anticipation of
removing the mask format overrides.

This also changes the textblobrandomfont test to fix the line spacing
and emoji handling.
