Rollup behavior alignment tests

We aim for behavior alignment with Rollup by running Rollup's own tests against Rolldown.

To achieve this, each test case in packages/rollup-tests/test proxies to the corresponding test in the rollup git submodule in project root.

The git submodule should have been initialized after running just setup when setting up the project, but you should also run just update-submodule to update the submodule before running the Rollup tests.

• just test-node-rollup will run rollup tests.
• just test-node-rollup --update will run and update the tests status.
