Subject: [PATCH] freetype: Fix function signatures to match without casts

Clang 16 has got a new stricter warning for casts of function types
(see https://github.com/llvm/llvm-project/commit/1aad641c793090b4d036c03e737df2ebe2c32c57).

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;
                                 ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
