gdksurface-win32.c: Call _gdk_surface_update_size() more

Browse Source 
The current resizing implementation in the GDK-Win32 backend is not
telling GDK early enough for Vulkan that a resize in the surface (i.e.
HWND) is done, so that GDK can re-create swapchain in time, which is
apparent on nVidia drivers (and AMD drivers that utilize the mailbox
presentation mode on Windows) when the HWND is being enlarged
interactively.

To work around this, bar a refactor in the Windows resizing/presentation
code, is to call _gdk_surface_update_size() when we really did resize
the HWND when we handle queued resizes via SetWindowsPos().

The existing call in gdksurface-win32.c in
_gdk_win32_surface_compute_size() remains required, otherwise the
surface won't display initially.

Thanks to Benjamin Otte for pointing this possibility out.
