Migrate `run-make/issue-14500` to new `rmake.rs` format

Part of rust-lang#121876 and the associated [Google Summer of Code project](https://blog.rust-lang.org/2024/05/01/gsoc-2024-selected-projects.html).

Note: I find suspicious that `libbar.a` is hardcoded and is not using the `STATICLIB` call to adapt to Windows platforms. Is this intentional? If not, this will need to be changed.

only find segs chain for missing methods when no available candidates

Fixes rust-lang#124946

This PR includes two changes:
- Extracting the lookup for the missing method in chains into a single function.
- Calling this function only when there are no candidates available.

Don't do post-method-probe error reporting steps if we're in a suggestion

Currently in method probing, if we fail to pick a method, then we reset and try to collect relevant candidates for method errors:

https://github.com/rust-lang/rust/blob/34582118afaf00b0eb2d209a90b181c7156b501c/compiler/rustc_hir_typeck/src/method/probe.rs#L953-L993

However, we do method lookups via `lookup_method_for_diagnostic` and only care about the result if the method probe was a *success*.

Namely, we don't need to do a bunch of other lookups on failure, since we throw away these results anyways, such as an expensive call to:

And:

This PR also renames some methods so it's clear that they're for diagnostics.

Use new utility functions/methods in run-make tests

Little cleanup using new functions/methods I added into the `run-make-support` library.
