Bugfix #21234: Autokey "insert only available" userpref inserts keys for all bones in an armature

-- 

Bugfix: When autokey is enabled, notifiers to refresh the animation editors *after* transforms finished for objects were missing.
While I understand the need to limit these to not doing this during transform, after transform, this lead to lag/inconsistent UI problems.

* Added 'Damped Track' Option to 'Make Track' Operator
* Improved the code of the 'Clear Track' operator to include other types of tracking constraint too
