  Various changes to pmap_ts_referenced()

  Move PMAP_TS_REFERENCED_MAX out of the various pmap implementations and
  into vm/pmap.h, and describe what its purpose is.  Eliminate the archaic
  "XXX" comment about its value.  I don't believe that its exact value, e.g.,
  5 versus 6, matters.

  Update the arm64 and riscv pmap implementations of pmap_ts_referenced()
  to opportunistically update the page's dirty field.

  On amd64, use the PDE value already cached in a local variable rather than
  dereferencing a pointer again and again.
