Extract tdp_mmu_root_match() to check if the root has given types and use
it for the root page table iterator.  It checks only_invalid now.

TDX KVM operates on a shared page table only (Shared-EPT), a mirrored page
table only (Secure-EPT), or both based on the operation.  KVM MMU notifier
operations only on shared page table.  KVM guest_memfd invalidation
operations only on mirrored page table, and so on.  Introduce a centralized
matching function instead of open coding matching logic in the iterator.
The next step is to extend the function to check whether the page is shared
or private

Missing a period at the end of the sentence.
