lok: preserve mouse event logic position and use in calc

When clicking in online Calc any of the  charts, shapes (and
other objects), sometimes the cell underneath is selected
instead. The problem is that the object is not correctly
recognised to be hit.

From lok we get the mouse event position in logic coordinates,
which we usually can just use in writer and impress. In calc
however we need the coordinates in pixels, so we transform them
before sending the mouse event to calc. Still calc also uses
common SdrObjects (chart, shapes,...), which operate in logic
coordinates. So in case of SdrObject we need to convert the
coordniates back from pixel to logic again, which causes
problems because conversion doesn't have access to the displaying
conditions on an stateless online client.
OTOH we already had the correct logic coordinates, and we can just
send them along. This is what this change does. It adds an optional
maLogicPosition to MouseEvent, which is filled with logic position
if those is known.
