Tools - Cleanup

[BrettMayson]

When merged this pull request will:

• Removes outdated tools
• Removes tools replaced by HEMTT equivalents

Some of the python I am not exactly sure what they do, if we need them, if they still work, etc.

If there are any that are useful they would be good to port to HEMTT instead of a python script here

I think stringtableduplicates.py's functionality is included in stringtable_validator.py fyi.

I know that extract_dependencies.py is still used for the website.

I'll let @PabstMirror weigh in if any more of these can be removed

[PabstMirror]

can probably drop search_privates.py and search_unused_privates.py

[BrettMayson]

There are probably more things that can be removed but I don't want this to just sit as a draft forever
