bcd5e4c216 Rip out glyf1 VarComposites 
In favor of separate VARC table.

ttGlyphSet does NOT yet know how to draw VARC table though.

The 9 failing tests are all VarComposite-related and need
to be updated with VARC equivalents eventually when we
add VARC support to subsetter and instancer.

Support sbix Glyphs with graphicType "flip" (#3433) 
* Support sbix Glyphs with graphicType = "flip"

Since iOS 17.4 beta, Apple introduced the "flip" graphic type for the sbix glyphs to reference the another glyph to be flipped by their render engine. Their use case is for directional emojis.

Example emoji: https://emojipedia.org/woman_walking_facing_right#technical

This is the example of the output XML after this PR:

```
<glyph graphicType="flip" name="u1F3C3.0.M.u27A1" originOffsetX="0" originOffsetY="0">
    <ref glyphname="u1F3C3.0.M" />
</glyph>
```

Before, it was just `<hexdata>` with some data in it.
