tools: add -d and -o args for catchpointdump net, like file, new info command

[cce]

Summary

This adds a new info command to catchpointdump, and adds the file command's -d and -o flags to the net command (a small change because net already shares code with file).

Test Plan

Tools only change, existing tests should pass.
