perf tests: Test annotate with data type profiling and rust

Exercise the annotate command with data type profiling feature on the
rust runtime. For that add a new shell test, which will profile the
code_with_type workload, then annotate the result expecting to see some
data structures from the rust code.

Committer testing:

  root@number:~# perf test 'perf data type profiling tests'
   83: perf data type profiling tests                            : Ok

   83: perf data type profiling tests                            : Ok
  root@number:~# perf test -vv 'perf data type profiling tests'
   83: perf data type profiling tests:
