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:
