d0d59d2f2c Add PaintScale* and Paint{Rotate,Skew}* variants 
This updates fonttools to match the latest draft COLRv1 spec at https://github.com/googlefonts/colr-gradients-spec/pull/290

Summary of changes:
- Added 8 new PaintScale* tables: with/without centers, uniform vs non-uniform
- Added *AroundCenter variants to PaintRotate and PaintSkew (default versions no longer have centerX/Y defaulting to origin)
- PaintRotate, PaintSkew and PaintComposite formats re-numbered

Partly revert "use 32-bit GlyphIDs in COLRv1 baseGlyphs and layers" 
This reverts commit 690080b14d9a4f193092ffc172a39b3e212d307c.

We keep 16-bit GlyphIDs for COLRv1 tables, at least for now
https://github.com/googlefonts/colr-gradients-spec/pull/24

I keep the GlyphID32 converter in case we may need it in the future.
