Update base for Update on "Install libcpp from release package other than apt-get"

A few changes

1. Use the release package from https://releases.llvm.org/ to install libcpp, so we can install from different linux in addition to Ubuntu
2. Seperate out the qnn version and the url to a seperate file, for better versin management in the future
