Rollup merge of #154586 - jdonszelmann:record-rerun, r=clubby789,jieyouxu

Record failed tests with `--record`, and rerun them with `--rerun`

This adds two parameters to `x test`:

## `--record`

Writes a file, by default `build/failed-tests`, but this can be overwritten with
```toml
[build]
record_failed_tests_path = "somepath"
```
with a list of all tests that fail that run.

## `--rerun`

Looks for the failed-tests file, parse it, and attempt to rerun only those tests. No cli-arguments are necessary, i.e.
```
x test tests/ui --record
x test --rerun
```

Will run all failed uitests. No need to pass tests/ui to the rerun invocation.

The last commit is a little awkward, but I think it's the best way to make it so that we *first* run all tests that have to be rerun, and *then* rerun tests passed through the cli.

This makes it so:
```
x test tests/ui --rerun
```
will *first* rerun failed tests, some of which may be uitests, if any fail it quits and reports failed tests, but if all pass it will run all normally passed tests. In other words, only if all previously-failed tests pass on the rerun, we then also run uitests.
Without the last commit, this would instead just run all uitests, since the failed tests form a subset of all uitests. I think that's less useful.

Website | Getting started | Learn | Documentation | Contributing

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.

Why Rust?

  • Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrated with other languages.

  • Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.

  • Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).

Quick Start

Read “Installation” from The Book.

Installing from Source

If you really want to install from source (though this is not recommended), see INSTALL.md.

Getting Help
