* drop empty lines when diffing output * replace expected css with optimized lightningcss output Lightning CSS generates a more optimal CSS output. Right now the tests are setup in a way that both the generated css and expected css are run through `lightningcss` to make sure that the output is concistent for the `stable` and `oxide` engines. But this also means that the expected output _could_ be larger (aka not optimized) and still matches (after it runs through lightningcss). By replacing this with the more optimal output we achieve a few things: 1. This better reflects reality since we will be using `lightningcss`. 2. This gets rid of unnecessary css. 3. Removed code!
