Description of problem:

Add a CSV3 ioctl command to enable interaction with the Linux KVM,
allowing requests to update the page attribute status of the
current CSV3 VM.

When a GPA range changes from the decrypted to the encrypted state,
we invoke this new ioctl command, and the Linux KVM will release the
pages corresponding to the GPA range's decrypted mapping. This is
particularly useful when the CSV3 frequently decrypts and encrypts a
large number of pages.
