perf test: Introduce --list-workloads to list the available workloads 



Using it:

  $ perf test -w noplop
  No workload found: noplop
  $
  $ perf test -w
   Error: switch `w' requires a value
   Usage: perf test [<options>] [{list <test-name-fragment>|[<test-name-fragments>|<test-numbers>]}]

      -w, --workload <work>
                            workload to run for testing, use '--list-workloads' to list the available ones.
  $
  $ perf test --list-workloads
  noploop
  thloop
  leafloop
  sqrtloop
  brstack
  datasym
  landlock
  $

Would be good at some point to have a description in 'struct test_workload'.
