[ot-font] Don't pre-load cmap table

Now that we have get_h_advances() and get_nominal_glyphs() implemented, the
overhead of doing a proper atomic load would be once per run, NOT once per
glyph.  So, no need to pre-load the tables to avoid that overhead.

As such, hb_ot_font_set_funcs() has become really cheap.  Can *finally* make
it be default font functions on all newly created fonts!
