build: add npm_integration_test && angular_integration_test (#33927)

* it's tricky to get out of the runfiles tree with `bazel test` as `BUILD_WORKSPACE_DIRECTORY` is not set but I employed a trick to read the `DO_NOT_BUILD_HERE` file that is one level up from `execroot` and that contains the workspace directory. This is experimental and if `bazel test //:test.debug` fails than `bazel run` is still guaranteed to work as  `BUILD_WORKSPACE_DIRECTORY` will be set in that context

* test //integration:bazel_test and //integration:bazel-schematics_test exclusively

* run "exclusive" and "manual" bazel-in-bazel integration tests in their own CI job as they take 8m+ to execute

```
//integration:bazel-schematics_test                                      PASSED in 317.2s
//integration:bazel_test                                                 PASSED in 167.8s
```

* Skip all integration tests that are now handled by angular_integration_test except the tests that are tracked for payload size; these are:
- cli-hello-world*
- hello_world__closure

* add & pin @babel deps as newer versions of babel break //packages/localize/src/tools/test:test

@babel/core dep had to be pinned to 7.6.4 or else //packages/localize/src/tools/test:test failed. Also //packages/localize uses @babel/generator, @babel/template, @babel/traverse & @babel/types so these deps were added to package.json as they were not being hoisted anymore from @babel/core transitive.

NB: integration/hello_world__systemjs_umd test must run with systemjs 0.20.0
NB: systemjs must be at 0.18.10 for legacy saucelabs job to pass
NB: With Bazel 2.0, the glob for the files to test `"integration/bazel/**"` is empty if integation/bazel is in .bazelignore. This glob worked under these conditions with 1.1.0. I did not bother testing with 1.2.x as not having integration/bazel in .bazelignore is correct.
