UI: remove unnecessary confirmation popups

This makes a number of operators no longer ask for confirmation, rather it will
show an info message after performing the operation. Ref T37422 for decision. In
particular, these were changed:

* Delete objects, bones, keyframes, masks, mask curves, motion tracks, markers.
* Clear and delete keyframes in the 3D view.
* Align bone to parents.
* Separate bones from armature.
* Group/ungroup metastrips in sequencer.
* Copy/paste objects to/from buffer.
