Add Racket optimisation pipeline (#5836)gh-9905

This adds a Racket optimisation pipeline view by reusing the existing
LLVM-focused optimisation pipeline UI. A Racket-specific pass parser
translates its output into passes for the UI to present.

This new Racket optimisation pipeline view is currently only enabled for
Racket nightly, as it depends on [recent
changes](https://github.com/racket/racket/pull/4842) to Racket's
compiler output to function.

This also extends the opt pipeline view to allow customising the
function selector label as well as the options and filters for each
compiler where needed.
