Issue #2191 - Remove as much old fontconfig support as needed for Harfbuzz update.

Browse source 
Based on Mozilla bugs 1119128, 1285533, and 1421964.

gfx.font_rendering.fontconfig.fontlist.enabled is no longer available.

gfxFontconfigUtils.h still exists, and will be removed in another commit. Just
need more research on bug 1385029.
