KVM: x86/mmu: Add Suppress VE bit to EPT shadow_mmio_mask/shadow_present_mask

To make use of the same value of shadow_mmio_mask and shadow_present_mask
for TDX and VMX, add Suppress-VE bit to shadow_mmio_mask and
shadow_present_mask so that they can be common for both VMX and TDX.

TDX will require shadow_mmio_mask and shadow_present_mask to include
VMX_SUPPRESS_VE for shared GPA so that EPT violation is triggered for
shared GPA.  For VMX, VMX_SUPPRESS_VE doesn't matter for MMIO because the
spte value is defined so as to cause EPT misconfig.
