Actions are either locked to a specific ID type, or "floating". Actions in the floating state are now locked when they are assigned to an ID block. Previously (rB94b99b5d4a7c20cf2) this was done at evaluation time, which caused various problems: - The ID type was set on the evaluated copy, and inconsistently flushed back to the original. - A newly created Action could not be assigned to an Action constraint, unless a depsgraph evaluation was be forced first. This is now resolved by calling `BKE_animdata_set_action()` to set the action (instead of direct assignment) where possible, and calling `BKE_animdata_action_ensure_idroot()` otherwise.
