Add --benchmark-options option

[sjakobi]

…in analogy to --test-options.

For now, I can use cabal run to run benchmarks with arguments, but that doesn't work for benchmarks that try to open files by relative paths.

Note #6114 (comment) which is somewhat relevant.

I took a shot at this in #6224. It mostly works, although there are some unresolved issues to work out, such as the one observed in #6224 (comment).

Just to quickly say I ran into this and would appreciate this feature, is it still on the agenda somewhere?

@Boarders It was released in cabal-install-3.2.0.0.
