console/win32: allocate shareable display surface
Introduce qemu_win32_map_alloc() and qemu_win32_map_free() to allocate shared memory mapping. The handle can be used to share the mapping with another process. Teach qemu_create_displaysurface() to allocate shared memory. Following patches will introduce other places for shared memory allocation. Other patches for -display dbus will share the memory when possible with the client, to avoid expensive memory copy between the processes.
