KVM: x86/mmu: free up bit 10 of PTEs in preparation for MBEC
Update SPTE_MMIO_ALLOWED_MASK to allow EPT user executable (bit 10) to
be treated like EPT RWX bit2:0, as when mode-based execute control is
enabled, bit 10 can act like a "present" bit. Likewise do not include
it in FROZEN_SPTE.
No functional changes intended, other than the reduction of the maximum
MMIO generation that is stored in page tables.
