Allow configuration of external embedder FreeType

Add a public config to fxfreetype to make includes visible and provide a
freetype_common group as a public dependency on fxcrt. freetype_common
switches between fxfreetype and //build/config/freetype, which gives
embedders the flexibility to configure the source of FreeType.
