add cl-quil-benchmarking system quilc-perf for perf. benchmarking

This is part of issue "Investigate performance at 72-150 qubits #565".

new modules:
  benchmarking/quilc-perf.lisp - primarily exports
    benchmark-nq function to get timings as nQ increases for various
    chip and program types

  benchmarking/quilc-mon-prof.lisp - builds on quilc-perf.lisp and is
    for monitoring and profiling, as opposed to simple benchmarks, and
    is a WIP.

Makefile - add targets to run benchmark-nq a couple of ways

cl-quil-benchmarking.asd - add new module quilc-perf and depend on 3
  additional systems: metering, qvm-app, sb-sprof
