Rename fuchsia builder and bump Fuchsia

This PR renames the fuchsia builder as requested in rust-lang/rustc-dev-guide#1989 (review) and bumps Fuchsia.

This includes the quality-of-life improvements for developers in https://fxrev.dev/1061894. It also removes the wasm target, which should speed up the build a little.

The new name of the builder is `x86_64-fuchsia` because I think `x86_64-gnu-fuchsia` would be confusing and put too much emphasis on the host target. (In terms of triples, we are targeting `x86_64-unknown-fuchsia` from `x86_64-unknown-linux-gnu`.) Someone on the infra team should weigh in here.

After this lands, we should update the docs in the rustc-dev-guide again.
