Add some useful info printouts to debug builds

Specifically when building in debug mode, we now:

* Display all features on load, including skipped and internal ones,
  sorted by internal name instead of display name.

* Print the names of all matched gametype tags after the feature list.

* Add an sst_dbg_getcmdcb command to get the address of a command
  callback for quick breakpoint insertion or Ghidra lookup.

* Add an sst_dbg_sendtables command to dump out the full ServerClass
  tree to help get names for entprops.txt. Note: this output is very
  long so you'll likely need to log console output to a file to be able
  to read it all.

There's a bunch of developer experience and debug help stuff I want to
get done eventually. This is just a very small piece, but it's a start.
