[PATCH v4 1/7] hidclass.sys: Make sure a desktop is created for the driver process.

[Rémi Bernon]

From: Rémi Bernon

This was previously automatically done when user32 was loaded, but since
the move of __wine_send_input to win32u, we do not need to load it any
more. Make sure we have a desktop or WM_INPUT messages won't be sent by
wineserver.
