rustdoc: remove unused CSS class `in-band`

Since a7c25b29575c17434406b69773f8c2961af343b3 removed `in-band` from code
headers, the only remaining uses of the `in-band` class are:

https://github.com/rust-lang/rust/blob/02cd79afb8080fce8c8ce35533c54d8ecf8f390e/src/librustdoc/html/render/write_shared.rs#L520-L521

https://github.com/rust-lang/rust/blob/02cd79afb8080fce8c8ce35533c54d8ecf8f390e/src/librustdoc/html/templates/print_item.html#L2-L3

https://github.com/rust-lang/rust/blob/02cd79afb8080fce8c8ce35533c54d8ecf8f390e/src/librustdoc/html/render/context.rs#L637-L638

https://github.com/rust-lang/rust/blob/02cd79afb8080fce8c8ce35533c54d8ecf8f390e/src/librustdoc/html/render/mod.rs#L368-L369

https://github.com/rust-lang/rust/blob/02cd79afb8080fce8c8ce35533c54d8ecf8f390e/src/librustdoc/html/render/mod.rs#L401-L402

https://github.com/rust-lang/rust/blob/02cd79afb8080fce8c8ce35533c54d8ecf8f390e/src/librustdoc/html/static/js/main.js#L525

Since all of these uses are nested below `h1.fqn`, we can get rid of it,
and the support code that was used for when `in-band` was part of item
rendering.
