Cleanup: animation, remove `BONE_UNKEYED` flag

Remove the `BONE_UNKEYED` flag. It was only written (set/cleared) but
never actually read.

Also remove `framechange_poses_clear_unkeyed()` as its only function was
to clear the `BONE_UNKEYED` flag. It wasn't used anywhere either.

The only code that used the flag was the `extract_pose_from_action()`,
which was removed in 2869ce6cfab3aa4ff471bef6e49ac6fe15426247 (2009).

No functional changes.
