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.
