Add OpenMC benchmark

[amklinv-nnl]

Description

OpenMC is an open source Monte Carlo transport simulation code.

Dependencies: FIXME:Add a list of any dependencies.

Fixes issue(s): FIXME:Add list of relevant issues.

Type of Change

• { } Adding a system, benchmark, or experiment
• { } Modifying an existing system, benchmark, or experiment
• { } Documentation update
• { } Build/CI update
• { } Benchpark core functionality

Checklist:

If adding/modifying a system:

• { } Create a new directory for the system and a new system.py file
• { } Add a new dry run unit test in .github/workflows
• { } System appears in System Specifications table in docs catalogue section

If adding/modifying a benchpark:

• { } Add a new application.py and (maybe) package.py under a new directory
  for this benchmark
• { } Configure an experiment
• { } Benchmark appears in Benchmarks and Experiments table in docs catalogue
  section

If adding/modifying a experiment:

• { } Extend experiment.py under existing directory for specific benchmark
• { } Define a single node and multi-node experiments

If adding/modifying core functionality:

• { } Update docs
• { } Update .github/workflows and .gitlab/ci unit tests (if needed)

Thank you for your contribution, @amklinv-nnl! It will be great to have openmc in benchpark.

Which programming model does this benchmark use (e.g., MPI, OpenMP, CUDA, ROCM)? On what platform are you running them (e.g., x86 with MPI, x86 with OpenMP or both, any GPU machines)?

To integrate this into Benchpark, we need to add benchpark/experiments/openmc/ProgrammingModel/ramble.yaml, which would then describe how to run a specific test. Happy to help writing this if you provide what you are currently doing.
