[WIP] Add modifier for affinity package

[rfhaque]

Description

[WIP] Adding a modifier that prints thread/core/gpu affinity for an experiment.

• Potentially closes Binding info #480.
• Update docs
• Update .github/workflows and .gitlab/ci unit tests (if needed)

@dyokelson We want to use this modifier to record the affinity. Please let Riyaz know how the data should be output (json format - any more details?) and where the file should be written so that we can inject it into the .cali file.

[pearce8]

line 25 should be:

depends_on("cuda", when="+cuda")

@dyokelson The modifier can now generate the JSON output. Usage:

bin/benchpark system init --dest=tioga llnl-elcapitan rocm=5.5.1 +gtl compiler=cce
rm -rf saxpy; ../bin/benchpark experiment init --dest saxpy saxpy +rocm~cuda~openmp caliper=mpi affinity=rocm
benchpark setup saxpy tioga <workspace>
ramble setup ...
ramble on ...

The JSON file will be available at {experiment_dir}/affinity.rocm.json

@nhanford @pearce8 I have only tested this on lassen(cuda) and tioga(rocm). We need to test if the modes are output correctly, in particular there seems to be no mpi+openmp mode

@dyokelson please take a look, does this work for injecting into Caliper attributes?

@rfhaque Please add docs - how to use etc.
