Cleanup: Hide implementation details for ED_keyframe_keylist.

For T78995 we want to change the data structure of keylists to
improve performance. (Probably a Vector with bin-search capabilities).

This patch hides the internal structure of the keylists behind `AnimKeylist`
structure. This allows us to change the internals without 'breaking' where it is
being used.

The change adds functions to create, free, find and walk over the
keylist.
