KVM: selftests: Add support for nested NPTs
Implement nCR3 and NPT initialization functions, similar to the EPT
equivalents, and create common TDP helpers for enablement checking and
initialization. Enable NPT for nested guests by default if the TDP MMU
was initialized, similar to VMX.
Reuse the PTE masks from the main MMU in the NPT MMU, except for the C
and S bits related to confidential VMs.
