Cleanup/Refactor: Move animdata read/write code into generic ID handling.

There is no reason at all for each ID read/write callbacks to have to
deal with this generic, common data explicitely. Generic ID read/write
code is the place to handle such data (just like asset, liboverride,
etc. data are handled already).

Note behavioral change expected here.
