Move SkLCDFontConfig out of blink API.

SkFontLCDConfig is being phased out in favor of explicitly stating the
pixel geometry on the SkSurface (instead of on a global). Blink itself
does not even use these values anymore, since the surface it uses is
provided by cc/. Since blink is no longer interested in these values,
set the current global directly in content/ instead of doing so
indirectly through blink.
