Migrates the schematics-cli tests to `rules_js`. Notably a little extra logic was needed here as the tests were relying on the built npm package at runtime, resolvable via it's "package name". To address this, we manually link the package for the test at runtime. The spec file is moved into a separate folder for this reason, so that we don't accidentally expose the schematics CLI package for unexpected reasons.
