[NTOS:MM][NTOS:CC] Rewrite some cache memory management functions (#7510)
Use section object pointer with byte offset instead of using base address. This simplifies the Mm functions themselves and also the code in Cc that calls them.
Also add minor fixes for MmFlushSegment and MmPurgeSegment.

cb74d9e24e [NTOS/CC] Fix broken usage of _SEH2_FINALLY
Finally handlers are - unlike except blocks - not part of the function they are in, but separate functions, which are called during unwind. PSEH implements them on GCC using nested functions. While "return" from a finally handler is allowed with native SEH, it's handled by the compiler through an extra unwinding operation using _local_unwind, WHICH IS NOT SUPPORTED BY PSEH! With PSEH, returning from a finally handler does not return from the function, instead it will only return from the finally handler and the function will continue below the finally handler as if there was no return at all. To fix this, the return is removed and an additional success check is added.
Also use _SEH_VOLATILE to make sure the variable assignment is not optimized away by the compiler and add zero out the result parameters on error.

b2fcd27aaa [NTOS/CC] Fix calls to CcRosEnsureVacbResident
The function returns BOOLEAN, not NTSTATUS! Also wrap it in SEH, because it can throw an exception on failure.

[NTOS:CC] Unintialize private cache maps before purging the cache section
Before purging the data cache of a certain section of a file from system cache, we have to unintialize the private cache maps of that section if a filesystem or any other component prompts the kernel to do so.
