Tuur Martens 10126e7710 [NTOS:MM] Fix VADs being inserted even though the quota would exceed 
Since we were charging the pool quota after the VAD insertion,
if the quota charge failed, the VAD would still have been inserted.
This commit attempts to resolve this issue by charging quota
before inserting the VAD thus allowing the quota charge to fail early.

Addendum to 884356a0. CORE-18028

Timo Kreuzer f606b36cff [NTOSKRNL] Fix a bug in MiDeleteVirtualAddresses 
When a PDE gets empty, we skip the address to the next PDE boundary, which might introduce an AddressGap, which wasn't handled before.

Jérôme Gardou d8cdb89fb0 [NTOSKRNL] Overhaul Cc and Mm relationship 
Previously, when creating a file section, Mm requested Cc to cache the file, then Cc would request pages from Mm, then Mm would request them back to serve its file-mapping role
Now, Mm does it all by itself. If file cahcing is requested by the FS driver, then Cc creates a file mapping and uses that to serve its purpose.

This is a rewrite of Cc
