Fixes #14784
This is an alternative to #14850 in which we actually perform url rewriting / rebasing ourselves. We ported a large portion of the URL-rewriting code from Vite (with attribution) to use here with some minor modifications. We've added test cases for the url rewriting so verifying individual cases is easy. We also wrote integration tests for Vite that use PostCSS and Lightning CSS that verify that files are found and inlined or relocated/renamed as necessary.
We also did some manual testing in the Playground to verify that this works as expected across several CSS files and directories which you can see a screenshot from here:
