CMake, Recent cuRVE and an ABM-like miniapp

[ptheywood]

• Add's CMake-based build system
• Updates cuRVE to a more recent version stripped out of FLAMEGPU/FLAMEGPU2
• Adds an ABM-like benhmark mini app, mocking up the FLAME GPU 2-like use-case of cuRVE in isolation.

Example is configured and built as the abm-benchmark miniapp.

Usage includes help, specify -v for verbose output and -vv for additional per iteration verbosity.

Todo

• add cuRVE error checking into the example and miniapp
• Clean up the miniapp source a little (docs, refactoring)
• Make the mini-app more realistic to test register pressure
• Add some validation of the miniapp beyond printing elements to stdout.
• Fix windows CI
• Address warnings generated by CUDA 11.5+ due to deprecation of pragma in third party code (not marked as imported with current CMake logic)
• Support running multiple scales in a single pass via multiple cli options? Or support config file based runs.

Ideally there should also be:

• Add unit tests of cuRVE itself
• Add the RTC version in here for isolated testing of RTC curve
• Add a reference non-cuRVE implementation of the mini-app (i.e. global mem SoA based implementation)

Prior to merging into master:

• Re-add cuRVE description info to the readme
