lavfi/vf_drawtext: fix memory management when destroying font face
Ref https://trac.ffmpeg.org/ticket/11152 According to harfbuzz docs, hb_ft_font_set_funcs() does not need to be called, as, quoted: ``` An #hb_font_t object created with hb_ft_font_create() is preconfigured for FreeType font functions and does not require this function to be used. ``` Using this function seems to cause memory management issues between harfbuzz and freetype, and could be eliminated. This commit also call hb_ft_font_changed() when the underlying FC_Face changes size, as stated on hardbuzz: ``` HarfBuzz also provides a utility function called hb_ft_font_changed() that you should call whenever you have altered the properties of your underlying FT_Face, as well as a hb_ft_get_face() that you can call on an hb_font_t font object to fetch its underlying FT_Face. ``` Finally, the execution order between hb_font_destroy() and hb_buffer_destroy() is flipped to match the order of creation of the respective objects.
