Optimise CLI Webpack configuration

[Mrtenz]

SWC was previously configured to output CJS, which means any imports would be transpiled to require. This means that any dependencies would also be loaded as CJS, even though an ESM version may be available. By changing SWC to output ES6 code and not transpiling any imports, Webpack loads potentially more ESM code which can be better optimised and tree-shaken.

Below are the old and new file sizes of the examples. For some examples, this change reduces the file size by 70%.
