Description

Now that we had code-splitting for a long time, this will use code-splitting for Rollup's own build as well and deduplicate shared dependencies between the CLI and rollup itself for the Node CommonJS build.

This should save a few bytes and make us have a sip of our own medicine. The ESM and browser builds will not use code-splitting as there is nothing to share code with.

Also updates some dependencies.

The CLI code has been moved from /bin/src to /cli (similar to how the browser code is in /browser) and the built CLI has been moved from /bin/rollup to /dist/bin/rollup.
