Adds missing test coverage for rustdoc's `--test-builder` option.

The existing test only covered the error case (non-executable builder). This PR
adds:
- A custom test builder that logs arguments and forwards to rustc
- A test verifying that `--test-builder` successfully invokes the custom
builder with rustc-style arguments
- Improved comments explaining both the error and success test scenarios

The test validates that custom builders can properly intercept and handle
doctest compilation.

Stabilize s390x `vector` target feature and `is_s390x_feature_detected!` macro

closes rust-lang#145649
closes rust-lang#135413
cc: rust-lang#130869
reference PR: rust-lang/reference#1972

# Stabilization report

## Summary

This PR stabilizes the following s390x target features:

- `vector`
- `vector-enhancements-1`
- `vector-enhancements-2`
- `vector-enhancements-3`
- `vector-packed-decimal`
- `vector-packed-decimal-enhancement`
- `vector-packed-decimal-enhancement-2`
- `vector-packed-decimal-enhancement-3`
- `nnp-assist`
- `miscellaneous-extensions-2`
- `miscellaneous-extensions-3`
- `miscellaneous-extensions-4`

Additionally, it stabilizes the `std::arch::is_s390x_feature_detected!` macro itself and stably accepts the target features listed above.

## Tests & ABI details

Only the `vector` target feature changes the ABI, much like e.g. `avx2` it will, depending on the ABI, pass vector types in vector registers. This behavior is tested extensively:

- [tests/assembly-llvm/s390x-vector-abi.rs](https://github.com/rust-lang/rust/blob/22a86f8280becb12c34ee3efd952baf5cf086fa0/tests/assembly-llvm/s390x-vector-abi.rs)
- [tests/codegen-llvm/s390x-simd.rs](https://github.com/rust-lang/rust/blob/22a86f8280becb12c34ee3efd952baf5cf086fa0/tests/assembly-llvm/s390x-vector-abi.rs)
- [tests/ui/abi/simd-abi-checks-s390x.rs ](https://github.com/rust-lang/rust/blob/22a86f8280becb12c34ee3efd952baf5cf086fa0/tests/ui/abi/simd-abi-checks-s390x.rs )

The remaining features don't influence the ABI, they only influence instruction selection. In stdarch we test that the expected instructions are in fact generated when the target feature is enabled.

## Implementation history

For `is_s390x_feature_detected!`:

- rust-lang/stdarch#1699
- rust-lang#138275
- rust-lang/stdarch#1720
- rust-lang/stdarch#1832

For `vector` and friends

- rust-lang#127506
- rust-lang#135630
- rust-lang#141250

## Unresolved questions

There is a fixme in [tests/ui/abi/simd-abi-checks-s390x.rs](https://github.com/rust-lang/rust/blob/22a86f8280becb12c34ee3efd952baf5cf086fa0/tests/ui/abi/simd-abi-checks-s390x.rs):

```
// FIXME: +soft-float itself doesn't set -vector
//`@[z13_soft_float]` compile-flags: --target s390x-unknown-linux-gnu -C target-cpu=z13 -C target-feature=-vector,+soft-float
//`@[z13_soft_float]` needs-llvm-components: systemz
```

I'm not sure whether that blocks stabilization?

---

The implementation first extracts the listed target features into their own `s390x_target_feature_vector` rust feature, and then stabilizes that. best reviewed commit-by-commit

[rustdoc] Replace `print` methods with functions to improve code readability

We have a lot of `print` methods, making it quite tricky to know what the types we're manipulating are.

We did something similar with `Clean` trait a few years ago (the first PR was rust-lang#99638, followed by a lot of them).

Each commit replaces one type for easier review.
