The kernel command line can contain settings affecting the availability
of cpu features, eg. "tsx=on". This series adds the kernel command line
to the cpu flags cache and declares the cache invalid if the current
kernel command line differs.

Fixes https://bugzilla.redhat.com/show_bug.cgi?id=1953389.

  virQEMUCaps: Add kernel command line
  virQEMUCapsCachePriv: Add kernel command line
  qemu: Invalidate capabilities cache on kernel command line mismatch
