x86/kvm/mmu: make space for source data caching in struct kvm_mmu

Browse source

In preparation to MMU reconfiguration avoidance we need a space to
cache source data. As this partially intersects with kvm_mmu_page_role,
create 64bit sized union kvm_mmu_role holding both base and extended data.
No functional change.
