Add build scripts for early exascale architectures to the master branch

[mewall]

Describe the bug
Work on builds for exascale architectures are not yet in the master branch, they are in the "tulip" and "jlse-intel" branches. Add build scripts to the master branch for these architectures and modify CMakelists.txt as needed to support these cases in a way that doesn't break other builds.

Based on the discussion this morning, I will register my suggestion of adding 'CPU_VENDOR' and 'GPU_VENDOR' (or 'ACC_VENDOR'?) as switches in the Cmake/build process.

Tulip build and install now works using the CMakelists.txt file in master. Tests are failing, however, with the below error. Forwarded to consultants for advice.

This issue will be addressed when PR #527 is merged into master
