Micha Reiser 31db1b6e16 Remove long Iterator::chain sequence in RuleCodePrefix::iter (#10452) ...

## Summary

This PR removes the `Iterator::chain(...)` sequence in
`RuleCodePrefix::iter()` with `Vec::expand` to avoid an
overlong-recursive types.

The existing `RuleCodePrefix::iter` method chains all rule group
iterators together. This leads to very long recursive types
`Chain<Map<Chain<Map<Chain<Map.....>>>>` (proportional to the number of
rule groups).

This PR rewrites the macro to use `Vec::extend` instead, which removes
the long recursive type (at the cost of introducing a potential
allocation).

## Alternatives

An alternative would be to use a stack allocated array by unrolling the
`Linter::iter` methods (generated by `EnumIter`).
I don't think it's worth the extra complexity, considering that
`RuleCodePrefix::iter` isn't a hot function.
