[PATCH 2/2] win32u: Don't activate window if it's already activated in set_window_pos.

[Santino Mazza]

From: Santino Mazza

This fixes a difference in behavior between Wine and Windows, where in Wine
it's possible to immediatly reactivate a window by calling SetWindowPos
inside the WM_ACTIVATE handler. In Windows this isn't possible.
