chore: Add Makefiles for dev-packages to make it convenient to run tests

You can now run specific e2e, browser-integration, node-integration and
node-core-integration tests by using `make` inside `dev-packages`.

Select the suite and you'll be given a fuzzy search prompt that you can type in
to filter or use arrow keys to select the test you want to run.

This is for running specific tests/test-apps.
