bootstrap: Explicitly mark the end of a failed test's captured output
While working on some compiletest stuff, I noticed that when bootstrap prints a failed test's captured output, there's no indication of where that output actually ends.
In addition to indicating where the captured output ends, this end marker also makes it easier to see the relevant test name when scrolling upwards in terminal output.
bootstrap: vendor `clippy_test_deps` too
This internal crate explicitly separates itself from the `rustc`
workspace, but it is needed for `./x test clippy` to work, including its
dependencies when building from a vendored `rustc-src` tarball.
Always build miri for the host in `x run miri`
Previously we were building Miri for the passed `--target`, which was wrong.

Make `x test distcheck` self-contained
Before, the checked components were extracted under the checked out source root, which caused us to test some weird combination of tarball + checkout sources/aritfacts/configuration.
Now `x test distcheck` works with an external temporary directory instead, which should make it self-contained. I also moved some config from the Dockerfile to the test itself, and fixed an issue in tidy that caused `x test tidy` to fail on tarball sources.
I also removed `.args(&builder.config.configure_args)`, because it was passing all kinds of crap from the CI config to the distcheck step, which was making it less reproducible.

Create a dedicated enum to abstract the different ways compiler-builtins
can be configured.
This also relaxes build.optimized-compiler-builtins to accept the path
of a library to match the behavior of <target>.optimized-compiler-builtins
override.
Extend the <target>.optimized-compiler-builtins bootstrap option to accept a
path to a prebuilt compiler-rt builtins library, and update compiler-builtins
to enable optimized builtins without building compiler-rt builtins.
Enforce in bootstrap that dist and install must have stage at least 1
This is a continuation of my efforts to fix staging in bootstrap after the stage0 redesign. This PR gets rid of all `compiler_for` usages in the `dist` steps 🎉 The only remaining usages are in the `test` steps, which are my next goal, and which will be the final boss.. both because they are quite tricky, and because most of the the rest of the steps have been already fixed.
The changes are relatively straightforward, `x dist` defaults to stage 2, so in that case we want to use a stage 1 build compiler for everything (except stdlib, but we usually use it even there because of uplifting).
What I didn't fix yet are the docs steps, because they are *very* implicit right now, and fixing them deserves its own PR.
The first commit reverts the tests that I accidentally removed in https://github.com/rust-lang/rust/pull/145340🤦♂️ I did it in this PR to avoid further git conflicts..
