KVM: x86/mmu: Move "dummy root" helpers to spte.h

Browse source

Move the helpers to get/query a dummy root from mmu_internal.h to spte.h
so that VMX can detect and handle dummy roots when constructing EPTPs.
This will allow using the root's role to build the EPTP instead of pulling
equivalent information out of the vCPU structure.

No functional change intended.
