Improve MCAM visibility and field debugging for CN20K NPC.

- Extend "mcam_layout" to show enabled (+) or disabled state per entry
  so status can be verified without parsing the full "mcam_entry" dump.
- Add "dstats" debugfs entry: reports recently hit MCAM indices with
  packet counts; stats are cleared on read so each read shows deltas.
- Add "mismatch" debugfs entry: lists MCAM entries that are enabled
  but not explicitly allocated, helping diagnose allocation/field issues.

debugfs file which clears state seems quite odd.
Does any user need this?
This looks like a crutch for badly written tests TBH.
