Major UT Overhaul (#16544)

* Removes old UT definition files (drone/travis)
* Adds concurrency definitions to the workflows
* Changes our workflows to be more in line with what /tg does
* Adds a workflow to build/commit TGUI
* Adds a workflow to build/commit changelogs

Add python version to dependencies.sh
Fix dme errors
Removes a bunch of not included files
Cache Opendream and add directory to check_grep.py
