WINTERMUTE: Add mappings for VKeyCodes->ScummVM KeyCodes

Fix bug #6654 (white chamber - some keys don't work)

Wintermute games on ScummVM used ScummVM keycodes for keyboard mapping,
whereas the game scripts only accepted Windows VKeyCodes. Therefore an initial
set of mappings are added and the debug room is now loading properly, when
HOME is pressed (Rest of the keys need to be tested in-game)
