Fix css.awt.XSystemDependentMenuPeer.getMenuHandle

...to return an ANY containing a 64-bit HYPER instead of a 32-bit LONG for
SYSTEM_WIN32 (which covers both 32-bit and 64-bit versions of Windows), so that
the HMENU value (which is effectively a void*) is not truncated for the 64-bit
build.

This should effectively be URE ABI compatible for the 32-bit build, as there the
HYPER value will fit into 32 bits, so extracting a LONG from the ANY should
still work.
