Leandro Santiago 69cbda5770 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.

  • libswresample implements audio mixing and resampling routines.
  • libswscale implements color conversion and scaling routines.

Tools

  • ffmpeg is a command line toolbox to manipulate, convert and stream multimedia content.
  • ffplay is a minimalistic multimedia player.
