[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

[NTOS:MM] Some fixes for NtCreatePagingFile().
...
- Correctly probe the FileName user pointer before capturing its contents.
- A paging file name with zero length is invalid too.
- Remember (TODO!) in the code that the lower bounds of the Safe*Size values
need to be checked too!

It's hardly understandable and doesn't really makes sense.
Furthermore, it breaks compatibility with 3rd party FSD that
don't implement such FSCTL.
Obviously, Windows doesn't do this.
