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:

move PaintFormat enum outside of Paint class nested scope 
When a TTFont is loaded with lazy=True, the otTables are only loaded upon BaseTable.__getattr__
when the requested attribute is not found in the instance __dict__.
Since the Paint.Format enum was defined at class level, every Paint instance, even when loaded
lazily, will have a 'Format' attribute and the magic decompile-on-missing-attribute will not
trigger, since the class attribute will be returned when the instance is missing one.

For this reason, and to not add further special cases, it's better to simply move this Paint.Format
enum class outside to the module level scope, and rename it PaintFormat.

[docs] Reorganise colorLib docs (#1936) 
Does not add any new documentation (there is already some documentation for user-facing functions). It just makes colorLib.builder the top-level documentation entry, because that’s the part the user needs to care about.
