resolves #1352

Documentation

N / A

Summary of Changes

1. Have standard CSS plugin honor none optimization setting
2. For CSS bundling, we still need to honor the contents of any plugin process
3. For JavaScript / Rollup we don't want to emit the original source contents either
4. In the standard HTML resource plugin, make sure "none" still pulls in the right final optimized contents
5. Update test cases

TODO

1. fix Windows build (probably a pathing issue in the test files)
2. We should probably create a ticket for a completely unbundled output, that doesn't even transform filename. Basically whatever your src/ contents are, that is literally what will be moved over and better clarify difference / distinction between none and unbundled - support generating a completely unbundled project #1367
