build_helper: try less confusing method names
build_helper's `*_silent` methods were likely called that way because they do not print the command being run to stdout. [In the original file this all makes sense](046e6874c4 (diff-5c3d6537a43ecae03014e118a7fe3321)). But later it also gained `*_suppressed` methods and the difference between `silent` and `suppressed` is far from clear.
So rename `run` (which prints the command being run) to `run_verbose`. Then we can call the methods that just run a command and show its output but nothing extra `run` and `try_run`.
`run_verbose` (formerly `run`) is unused from what I can tell. Should I remove it?

On `format!()` arg count mismatch provide extra info
When positional width and precision formatting flags are present in a
formatting string that has an argument count mismatch, provide extra
information pointing at them making it easiser to understand where the
problem may lay:
```
error: 4 positional arguments in format string, but there are 3 arguments
--> $DIR/ifmt-bad-arg.rs:78:15
|
LL | println!("{} {:.*} {}", 1, 3.2, 4);
| ^^ ^^--^ ^^ --- this parameter corresponds to the precision flag
| |
| this precision flag adds an extra required argument at position 1, which is why there are 4 arguments expected
|
= note: positional arguments are zero-based
= note: for information about formatting flags, visit https://doc.rust-lang.org/std/fmt/index.html
error: 4 positional arguments in format string, but there are 3 arguments

Fix#49384.
Added support for armv7-unknown-linux-gnueabi/musleabi
Fixes#63101
Some things that are not done and I hope someone can help me with:
* During the ci build of `armv7-unknown-linux-gnueabi` `openssl` must be built (to build cargo) but `openssl` does not yet support this target. This feels slightly like a chicken-and-egg problem, any feedback is welcome.
* Should I add any tests for any of these targets?
Unconfigure compiler unit test files during normal build
I haven't touched libstd though, it had a lot of tests and I'm not sure the people maintaining it want this.

Remove redundant method with const variable resolution
I've also removed a `bug!()` in const value relation code and replaced it with a `FIXME`. Now `ConstValue::Slice` and `ConstValue::ByRef` will simply fail to unify rather than ICEing, which seems more user-friendly for testers.
More questionmarks in doctests
This removes the other `unwrap`s in the macro doctests, replacing them with `?`. For now, we need to specify the main function including the return type, we can get rid of that once the return type suggestion for `fn main() { .. }` works correctly.
