This makes all bootstrap types except for `Compiler` and
`TargetSelection` `!Copy`. This makes it easier to modify them by adding
!Copy types in the future and comes at no cost of code clarity, the
impls were completely unused.

remove `llvm.assertions=true` in compiler profile
Having this set to true disrupts compiler development workflows for people who use `llvm.download-ci-llvm = true` because we don't provide ci-llvm on the `rustc-alt-builds` server. Therefore, it is kept off by default.

bootstrap: don't resolve symlinks for initial_cargo
I have put the following in my `config.toml`:
```toml
# Includes one of the default files in src/bootstrap/defaults
profile = "compiler"
change-id = 121203
[build]
cargo = "/usr/bin/cargo"
rustc = "/usr/bin/rustc"
rustfmt = "/usr/bin/rustfmt"
```
I have rustup installed from Arch's repos, which has all of the above paths be symlinks to `/usr/bin/rustup`. This works just fine with the `argv[0]` trick that rustup uses.
However, `bootstrap` resolves symlinks to check whether `cargo` exists and then uses the resolved path, so it ends up calling `rustup` directly expecting it to behave like `cargo`. Which it doesn't.
This PR removes the canonicalization step, in turn fixing the issue, but sacrificing a pretty error message. However, this exact thing is checked by `x.py` in advance, so I hope it is not a big deal?

+ Do not resolve symlinks (as this may break rustup)
+ Check version not just for rustc, but also for cargo.
+ Check that the program's self-reported name
matches the expected name (such as "rustc" or "cargo").

This profile originally made sense when download-ci-llvm = if-unchanged
didn't exist and we had the bad tradeoff of "never modify or always
compile".
Thankfully, these grim times are over and we have discovered clean
water, so the only differentiator between the two profiles is the
codegen profile having LLVM assertions. Adding them doesn't cause that
much of a slowdown, <10% on UI tests from an unscientific benchmark.
It also had LLVM warnings when compiling, which makes sense for every
compiler contributor brave enough to compile LLVM.
The way I removed is by just issueing a nice error message. Given that
everyone with this profile should be a contributor and not someone like
a distro who is more upset when things break, this should be fine.
If it isn't, we can always fall back to just letting codegen mean
compiler.

create stamp file for clippy
Due to missing stamp file, we were downloading (and applying nix patches if enabled) continuously every time `Config::download_clippy` was called. This change fixes that by creating stamp file at the end of the function.

Support configuring the set of codegen backends to build per host triple
This allows building the compiler itself with one backend while using another backend at runtime. For example this allows compiling rustc to wasm using LLVM, while using Cranelift at runtime to produce actual code. Cranelift can't compile to wasm, but is perfectly capable of running on wasm. LLVM can compile to wasm, but can't run on wasm. [^1]
[^1]: The prototype of this still requires a couple of other patches.

src/bootstrap runs git to find the root of the repository, but this can
go awry when building in MSYS for the mingw target. This is because
MSYS git returns a unix-y path, but bootstrap requires a Windows-y path.

Netbsd10 update

Previously, we were trying to install all doc files under "share/doc/rust"
which caused `rust-installer` tool to create backup files (*.old) due to filename
conflicts. With this change, doc files is now installed under "share/doc/{package}",
where {package} could be rustc, cargo, clippy, etc.

always run `configure_linker` except for mir-opt tests
`configure_linker` now runs consistently unless it's for mir-opt tests. Previously `!= "check"` condition was causing dirt in the cargo cache between runs of `x anything-but-not-check` and `x check`.

Add instructions of how to use pre-vendored 'rustc-src'
This PR closes #110163.
I had to move the URL to the left, making it not aligned as it is three lines above, but the tidy check would yell at me otherwise. If that's not acceptable, I'd love some suggestions on how to make it better.
One question: in the original issue (https://github.com/rust-lang/rust/issues/110163#issuecomment-1502647562), it was suggested to mention how to download specific commit tarballs; however, it was said it's not documented anywhere, so I did not include that yet. If there is a want to have that, I'd gladly amend the commit.
