KVM: x86/mmu: Track shadow MMIO value on a per-VM basis
TDX will use a different shadow PTE entry value for MMIO from VMX. Add a
member to kvm_arch and track value for MMIO per-VM instead of a global
variable. By using the per-VM EPT entry value for MMIO, the existing VMX
logic is kept working. Introduce a separate setter function so that guest
TD can use a different value later.
