KVM: x86/mmu: pull page format to a new struct

Structs kvm_mmu ("build page tables") and kvm_pagewalk ("walk page
tables") share a piece of common functionality, namely "looking at PTEs".
Both of them have code to check is a specific access (described by
PFERR_* constants) is allowed by a PTE, and both of them also validate
that reserved bits are zero on the respective page tables page tables;
for SPTEs the code is only there to check internal consistency, but in
this case it is indeed shared via struct rsvd_bits_validate.

In preparation for sharing more PTE parsing code between struct
kvm_pagewalk and struct kvm_mmu, create a new struct that contains all
precalculated tables, including the data that is extracted from the
CPU role.  For now only struct kvm_pagewalk uses it.
