Hans Goudey 1f92fd7577 Refactor: Use AttrType instead of CustomData type in attribute API
Change `eCustomDataType` to `bke::AttrType` for uses of the attribute
API (the `AttributeAccessor` one anyway). I didn't touch any values that
might be saved in files; those should be handled on a case by case basis.

Part of #122398
