Revert "Remove subpixel positioning implies no bytecode hinting."

This reverts commit 880768032d7bd1528dc84f5b4408d4fa418bae7d.

Reason for revert: Pixel tests, and gfx tests can't handle hinting.

Original change's description:
> Remove subpixel positioning implies no bytecode hinting.
> 
> SkTypeface_FreeType::onFilterRec currently assumes that if we're asked
> to do subpixel positioning, don't do bytecode hinting. The idea was that
> both could not be satisfied at the same time, so pick something. This is
> no longer true, as with the v40 interpreter it is possible to get
> subpixel positioned but bytcode hinted glyphs.
