Improve the development experience in debug=assets mode by reducing the
number of requests to the server. We are adapting the solution used for
the JS files to the CSS files. This solution consists of no longer
sending all the files separately, but sending only the bundles
associated with their sourcemap. This allows us to keep the same
debugging experience while drastically reducing the number of requests
to the server.
Benchmark:
saas 14.2 917 requests domcontentloaded after 3.76s
master (bundling du js) 299 requests domcontentloaded after 2.03s
branch (bundling js+css) 36 requests domcontentloaded after 1.01s
