Roadmap #850

I think we need a bit of a roadmap to get the project back on track again. We're pretty out of date with WPT at this point, and CI is failing. I think the easiest way to get back on track is the following:

• Fix CI Update MSRV to 1.60.0 #849
• Fix the no_std support landed a few months ago and complete it, or revert it if it's not working
  • Fix no_std Support for idna #843
  • no_std support for the url crate #831
  • no_std support for all crates #717
• Improve WPT runner to support ignoring certain tests
• Update WPT files and disable all failing tests

At that point we can figure out what exact new tests we are failing on. We should then determine which test failures relate to which spec changes, and open individual issues for implementing those changes.

I am hoping that improving the testing infrastructure and making sure CI works well again allows other contributors to implement individual spec changes easially. I'm hoping we can get back to 100% compliance by the end of the year.
