Herb Derby f29cb70281 Revert "Introduce SkGlyphSourceBuffer"
This reverts commit 77c53087c1.

Reason for revert: Breaks some windows builds

Original change's description:
> Introduce SkGlyphSourceBuffer
> 
> SkGlyphSourceBuffer provides a system for taking rejected glyphs from
> one glyph drawing stage, and turns them into the source for the next stage.
> It is rarely used, so it tries to conserve memory.
>
