This PR updates the rollup executor such that it produces.d.ts files matching the output bundle.

It also:

1. Use[name].esm.js and[name].cjs.js naming convention so Node/TSC doesn't have problems matching CJS files with their.d.ts file -- subsequent requires/imports from.cjs requires file extension to be included, which puts the burden on lib authors.
2. Updates theexports field to align with current best practice (import +default, notypes)
3. Generates types still when SWC is used

So a user using dual formats will see:

{"exports":{"./package.json":"./package.json",".":{"import":"./index.esm.js","default":"./index.cjs.js"}}

The types are inferred from file names e.g.index.cjs.d.ts orindex.esm.d.ts.
