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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
