largefiles: introduce "_lfstatuswriters" to customize status reporting

"lfutil.getstatuswriter" is the utility to get appropriate function to
write largefiles specific status out from "repo._lfstatuswriters".

This patch uses "stack" with an element instead of flag like
"_isXXXXing" or so, because:

  - the former works correctly even when customizations are nested, and
  - ensuring at least one element can ignore empty check
