This CL introduces a test runner and test cases under `pkg/dynamic_modules/test/`. These tests are end-to-end tests that specifically target the dynamic modules semantics. This includes: * semantics expecations on the program evolutions (e.g. libraries defined only once) * individual cases around the dynamic interface (callable, extensible, overrides). We should continue to add more test as we discover coner cases worth validating (e.g. mixins, constants, etc). The suite is not yet integrated to the test matrix, my plan is to do so after we have some initial targets set up.
