Ed Page 5b9799c6f4 refactor: Migrate from extern crate to test-support prelude
We now include the prelude in so many places, this simplifies how we can
present how `cargo-test-support` works.

Yes, this included some `use` clean ups but its already painful enough
walking through every test file, I didn't want to do it twice.
