KVM: x86/mmu: count KVM mmu usage in secondary pagetable stats.

Count the pages used by KVM mmu on x86 in memory stats under secondary
pagetable stats (e.g. "SecPageTables" in /proc/meminfo) to give better
visibility into the memory consumption of KVM mmu in a similar way to
how normal user page tables are accounted.

Add the inner helper in common KVM, ARM will also use it to count stats
in a future commit.
