Testing - Migrate QA DRAW tests to GTest (#818)

- Removed 37 DRAW test scripts from `tests/bugs/` directories
- Added 31 new GTest C++ test files in appropriate `GTests/` directories
- Removed corresponding QAcommands implementations from QABugs source files
- Updated CMake FILES.cmake files to include new test files
