Reënable iOS and tvOS tests

Summary:
Although the test suites have a handful of failing tests, the jobs themselves do not fail.

Let's get these tests back into the fold so that we may track our progress getting these back to a good state.

Run tests on Circle, and confirm everything is green: https://circleci.com/workflow-run/4dd1a84b-502d-4ad6-aa41-64c768392a6b

If you go into the test iOS and test tvOS jobs, you will see that we are collecting test results at the top. These results show the failing individual tests.
Closes https://github.com/facebook/react-native/pull/18171
