[NTOSKRNL] Implement write behind in Cc
...
For now, this is just a split between scan and flush that
were both done during lazy scan previously.
Lazy scan shouldn't perform any write operation, but only
queue a write behind operation.
Our implementation is far from the original, as it seems
our lazy scan should queue a write behind operation per
shared cache map. Right now, we only perform global
operation.

[NTOSKRNL] When growing a file, invalid the last VACB so that it can be refreshed
...
This will avoid corruption when a file size is little grown and read afterwards.
Up to now, FSD where reading 0es instead of expected data, causing corruption.
This fixes MS FastFAT not being able to mount a FAT volume in ReactOS, corrupting
the FAT.
This also fixes the CcSetFileSizes kmtest tests.
This is based on a patch by Thomas Faber.

going to transmit the buffer to BOOTVID.

This avoids performing a double-free (even though that's hidden by the
fact we use lookaside allocations for VACB), and it avoids freeing
a memory address at an uninitialized address.
We don't care about references here, the VACB was just allocated, never
linked and we're its only user.
