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.

Tuur Martens d31642c712 [NTOS:MM] Fix memory leak in NtAllocateVirtualMemory 
When an allocated VAD's insertion fails, the VAD is not freed. This commit attempts to fix this behaviour.

Tuur Martens cc99b9d96e [NTOS:MM] Fix MiInsertSharedUserPageVad preventing boot on x64 
Fix MiInsertSharedUserPageVad to not charge the system process pool quota.
Even though PsChargeProcessNonPagedPoolQuota itself checks if the process specified is the system process, this doesn't work here as we're too early into boot for the kernel to know what the system process is.

Tuur Martens 4f8bbd141e [NTOS:MM] Fix memory leak in MiMapViewOfDataSection 
If inserting the allocated VAD fails, MiMapViewOfDataSection will make no attempt to free the allocated VAD. Nor will it call MiDereferenceControlArea(ControlArea); like other failure return paths. This commit fixes this behavior.

[NTOS:MM] Implement Raise/Return pool quota functions 
This implements both MmRaisePoolQuota and MmReturnPoolQuota functions, which serve exclusively for quota pool management. The process manager communicates with the memory manager in a call of need to charge or return pool quota limits.

Victor Perevertkin 3f601122bc [NTOS:MM] Fix placing entries into MmNonPagedPoolFreeListHead 
When freeing pages, free page entries with pages num == 3 were
incorrectly treated as entries with pages num >= 4 and thus
their re-insertion was not triggered. That lead to non paged pool
fragmentation (can be triggered by kmtest:ExPools, for example)

Also, altered the index acquisition code for MmNonPagedPoolFreeList
entries so it looks more clear
