IMPALA-14847 (addendum): Add Iceberg's FilepathToHostsMapPB to large RPC logging

Iceberg DIRECTED exchanges use the by_node_filepath_to_hosts field
on ExecQueryFInstances. This could be an interesting component
of the size of ExecQueryFInstances RPCs for Iceberg queries.
This includes that size in the logging for large ExecQueryFInstances
RPCs. This is a separate commit to make it easier to backport the
original commit.

Example output:
W20260501 15:48:05.312261 3635660 coordinator-backend-state.cc:376]
  7b4d107519eb0809:6544a60b00000000] Large ExecQueryFInstances RPC:
  Total: 816.78 KB Shared TQueryCtx: 244.76 KB (243.67 KB from descriptor table)
  TExecPlanFragmentInfo: 1.50 KB ExecQueryFInstancesRequestPB: 570.52 KB
  num fragments: 2 num fragment instances: 2 num scan ranges: 1214
  filepath to host map: 237.55 KB

Testing:
 - Ran test_iceberg.py with a 512KB warning threshold and checked
   the output
