Sets up the test targets for integration tests with the new rule.
The targets will match the configuration of the previous integration
test setup (through the dictionary in a `bzl` file).
Note: We already add `setup_chromium` based on whether Chromium tests
run as part of this integration test. In a follow-up commit we can then
remove puppeteer and rely on the Bazel-managed version of Chromium.

Sets up a minimal CLI project for testing that `ng add @angular/localize`
works as expected. Schematic sub-packages are prone to CJS/ESM issues
due the overall framework packages being denoted as strict ESM.
This may not be an issue in the concrete scenario of `@angular/localize`
right now, but it is still good to have an integration test similar to
the tests we have for `@angular/core` schematics.
