Link PlusArg to emulator command line options
...
- adds a mutable singleton (PlusArgArtefacts) to store information
about Rocket PlusArgs
- adds methods to PlusArgArtefacts to emit C snippets that are
consumed by emulator.cc for correct argument parsing and help text
generation
- emits snippets in $(CONFIG).plusArgs via BaseCoreplex-set
ElaborationArtefacts
- modify emulator/Makefrag-verilator to include $(CONFIG).plusArgs
- cleanup help text (docstring) for existing PlusArgs
