layout/style/Loader use nsUnicharStreamLoader to load entire stylesheet before parsing. In order to utilize HTTP off-main-thread data delivery, we might be able to make nsUnicharStreamLoader to redirect ODA to stream transport thread pool. https://searchfox.org/mozilla-central/rev/01d27fdd3946f7210da91b18fcccca01d7324fe2/layout/style/Loader.cpp#1720

To be noticed that Stylo uses https://searchfox.org/mozilla-central/source/layout/style/StreamLoader.cpp to load the stylesheet. We'll need to make it OMT ODA capable as well.

This should move CSS loading Off MainThread, which should help pageload and/or responsiveness during pageload.
