Fix T72250: Select Boundary Loop

Edge Index display were not showing up after performing
"Select Boundary Loops" when in face selection mode. The operation
tagged the mesh that the selection was changed, but in the end this
didn't do anything within the depsgraph.

The fix changes this to recalc the geometry of the object. What also
syncs the selectmode flags. A better solution would be to update the
select flags only. But that could be done as future work when we have a
performance problems.
