Simplify and fix column determination code in wxGridStringTable.

The number of columns in the table is now (since r60717) stored in m_numCols,
so there is no need to get it from wxGrid any more. This is not only simpler
and faster but also more correct as the first row might not have the full
number of values yet.

Closes #15809.

Fix mouse wheel event coordinates in wxFrame in wxMSW.

The screen to client conversion for this event coordinates took the toolbar
height into account twice, resulting in a wrong value if the event was handled
in a frame that did have a toolbar.
