Martin Kustermann 96d40d1caa [vm/concurrency] Remove --(no-)enable-isolate-groups flag usage in tests
This is a preparation CL to remove the --enable-isolate-groups flag in
the VM.

The following tests were only running in --no-enable-isolate-groups and
are therefore obsolete now:

  - runtime/tests/vm/dart/regress_47468_test.dart
  - runtime/tests/vm/dart_2/regress_47468_test.dart
  - tests/lib/isolate/illegal_msg_function_test.dart
  - tests/lib_2/isolate/illegal_msg_function_test.dart

TEST=Changes tests only.
