1cb7e36bbd COLRv1: rename otData structs to remove 'V1' to match updated draft spec 
This is a breaking change (but the COLRv1 API was already marked as unstable and subject to change)

The changes in this PR are meant to match the changes from the COLRv1 draft spec at:

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.
