Remove unneeded test, and support code

The SkRemoteGlyphCache_ReWriteGlyph checked that glyphs of
desparation were not overwritten by glyphs coming from the
Renderer. Since the search of desparation is no longer, this
test is not needed.

In addition:
* Remove unused call prepareForDrawingPathsCPU.
* Cleanup some comments
