KVM: selftests: Add struct and helpers to wrap binary stats cache
Add a struct and helpers to manage the binary stats cache, which is currently used only for VM-scoped stats. This will allow expanding the selftests infrastructure to provide support for vCPU-scoped binary stats, which, except for the ioctl to get the stats FD are identical to VM-scoped stats. Defer converting __vm_get_stat() to a scope-agnostic helper to a future patch, as getting the stats FD from KVM needs to be moved elsewhere before it can be made completely scope-agnostic.
