Remove typeprof, it does not work on TruffleRuby

* typeprof uses RubyVM::InstructionSequence which is CRuby-specific.
* `typeprof --version` or `require 'typeprof'` fail with:
  typeprof-0.21.2/lib/typeprof/iseq.rb:4:in `const_missing': uninitialized constant TypeProf::ISeq::RubyVM (NameError)
* It contains a JS lockfile which causes dependabot alerts and PRs.
