Right Arrow Mouse Cursor in MSW without .rc

[DoltAlya]

There is no right arrow mouse cursor in Windows. But it's easy to create it from original arrow.

[VZ]

(In [73491]) Create wxCURSOR_RIGHT_ARROW on the fly from normal arrow cursor under MSW.

This allows to avoid having another cursor resource and also makes this cursor
nicer as rightarr.cur looks rather out of place under modern Windows systems.

Closes #14991.

it seems that wx/msw/rightarr.cur needs to be removed also from bakefile, I get:

/bin/install -c -m 644 ../include/$f /home/wojdyr/local/mingw32/include/wx-2.9/$f; \
done
/bin/install: cannot stat ‘../include/wx/msw/rightarr.cur’: No such file or directory

[VZ]

(In [73791]) Remove rightarr.cur which doesn't exist any more from files list.

This should have been part of r73491, see #14991.
