Fix T87983: Motion tracker button tooltips identical 

The tooltips for the tracker buttons were all equal (because they all
use the same operator).

This adds the `get_description` operator callback to the
`CLIP_OT_track_markers` operator and returns a more descriptive
tooltip for the different buttons.
