Martin Storsjö d88269c827 freetype: Fix function signatures to match without casts
Clang 16 has got a new stricter warning for casts of function types
(see 1aad641c79).

This new warning gets included as part of the existing error
diagnostic setting of -Wcast-function-type.

This fixes errors like these:

../src/hb-ft.cc:1011:34: error: cast from 'void (*)(FT_Face)' (aka 'void (*)(FT_FaceRec_ *)') to 'FT_Generic_Finalizer' (aka 'void (*)(void *)') converts to incompatible function type [-Werror,-Wcast-function-type-strict]
    ft_face->generic.finalizer = (FT_Generic_Finalizer) hb_ft_face_finalize;
                                 ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Behdad Esfahbod d6dbc0d175 [gi/ft] Silence warnings
gi doesn't understand that FT_Face is a pointer, and not bare struct.
So it skips these APIs anyway. Mark skip to silense the warning.

../src/hb-ft.cc:242: Warning: HarfBuzz: hb_ft_font_get_face: return value: Invalid non-constant return of bare structure or union; register as boxed type or (skip)
../src/hb-ft.cc:264: Warning: HarfBuzz: hb_ft_font_lock_face: return value: Invalid non-constant return of bare structure or union; register as boxed type or (skip)

But doesn't set new coords on the FT_Face. That's a lot more
work :(.
