input: margins are not selectable

* Fix col/row calculation in pointer-enter event; we did not take the
  margins into account.
* seat->mouse.col,row are now set to -1 if the cursor is inside the
  margins. That is, col/row are only ever valid when the mouse is
  actually over the grid, and not in the margins.
* Use regular 'left-ptr' mouse cursor when mouse is inside the
  margins, to not make the user think he/she can start a selection.

Besides making things clearer, this also fixes a crash that occurred
if you started a selection in e.g. the right margin.
