[WIN32K]
 - Slap *a bit* of sense in the way we use region objects and handles, avoiding a massive
orgy of handle allocations, locks, leaks and so on.
The motto here being "if you don't need a valid user-mode handle, then chances
are that you don't need one at all."
CORE-8506 #resolve #comment Stale region handles should not be passed anymore to user-mode
apps now.
