[Comgr] Add VERSION.txt file to track version

Instead of hardcoding the version into CMakeLists.txt, we can
create a seprate VERSION.txt file to track the version, and have
CMakeLists.txt pull from that file. The VERSION.txt file will also
make it easier for other python/bash scripts to query the Comgr
version
