Try using hb-ot-font.h font_funcs instead of hb-ft.h one. hb-ft needs fixing

I'd like to get a character width and height and am thinking to use
hb_buffer_get_glyph_positions()->x_advance .
I tried hello-harfbuzz with noto-emoji fonts:

<https://github.com/behdad/harfbuzz-tutorial/blob/master/hello-harfbuzz.c>
https://github.com/googlei18n/noto-emoji/tree/master/fonts
<https://github.com/googlei18n/noto-emoji/tree/master/fonts>
Seems hello-harfbuzz can get x_advance with NotoEmoji-Reqular.ttf but it
failed in FT_Set_Char_Size() or FT_Set_Pixel_Sizes() with NotoColorEmoji.ttf.
Even if I ignore the return value of FT_THROW(Invalid_Pixel_Size) from
FT_Set_Pixel_Sizes(), seems hello-harfbuzz does not return the accurate
x_advance.
Do you have any ideas to resolve it?
I'm using harfbuzz 1.3.2 and freetype 2.6.5 and testing U+1F469.
% ./hello-harfbuzz \
/usr/share/fonts/google-noto-emoji/NotoColorEmoji.ttf \
"👩"
Seems NotoEmoji-Reqular.ttf is a scalable font and NotoColorEmoji.ttf is a
fixed size font.
