wayland: Fix updating pointer cursor on Drag and Drop

Browse Source 
The logic to allow src/wayland to update the pointer cursor changed
to bypassing grabs in commit e69e4fa6, since it is nowadays the
responsibility of the DnD source to update the pointer cursor in reaction
to the negotiated action.

This is not entirely correct, and was done at the expense of regressions.
Change the logic so we explicitly check for a DnD grab existing, or use
the active focus instead (i.e. grab-aware). This fixes the regression, and
keep DnD cursor icons working.

This is a partial revert of commit e69e4fa6dbbd62677de61bcd2f5f3bec515e79ce.
