move enzyme flags from general cargo to rustc-specific cargo

A couple tests were using `BOOTSTRAP_CARGO` with `-Zbuild-std`, but that
stage0 cargo might not always be in sync with in-tree changes. In
particular, those tests started failing on the beta branch because the
older cargo couldn't find the library `Cargo.lock`, and then couldn't
build the latest version of `compiler_builtins` that had nightly changes.

change `download-ci-llvm` default from `if-unchanged` to `true`
Since https://github.com/rust-lang/rust/pull/129473 and https://github.com/rust-lang/rust/pull/130202, using `download-ci-llvm=true` is now the better default and it also fixes #130515.

The library path is needed when the toolchain has been configured with
`[rust] rpath = false`. Otherwise, building the reference book will get
an error when it tries to run rustdoc, like:
rustdoc: error while loading shared libraries: librustc_driver-2ec457c3b8826b72.so

set `download-ci-llvm = true` by default on "library" and "tools" profiles
It's very rare for developers to need to modify LLVM, so "if-unchanged" isn't a good default for "tools" and "library" profiles since it fetches the LLVM submodule to track changes.

avoid updating LLVM submodule during bootstrap unit tests
To test this, make sure you don't have `src/llvm-project` fetched and then set `llvm.download-ci-llvm=true` and run `x test bootstrap`.

add llvm-bitcode-linker and llvm-tools bins to ci-rustc's sysroot
https://github.com/rust-lang/rust/pull/130040 is [reverted](https://github.com/rust-lang/rust/pull/130292) because adding component binaries directly to the dist tarball of the compiler caused conflicts (see https://github.com/rust-lang/rust/issues/130291 and https://github.com/rust-lang/rustup/issues/4019). This PR solves the original problem without touching the dist tarball.

bootstrap: Print more debug info when `find_initial_libdir` fails
From looking at the failure messages printed by #129775, my hypothesis is that `rustc --print=sysroot` sometimes prints the wrong path when the rustc executable is hardlinked in multiple places, at least on my macOS system.
However, currently I don't have any concrete evidence of this actually happening. This PR therefore expands on #129775 by printing even more information on failure (including the actual rustc path), in the hope that when the failure next occurs we can confirm or reject the hypothesis that `rustc --print=sysroot` is printing the wrong path.

[bootstrap] Add support for building gcc and libgccjit
As `@eholk` summarized below:
> From my understanding, this change would add libgccjit as an optional component to the Rust distribution. This library is licensed under GPLv2 and currently we do not have any other components under that license so it would be a new license, and one that is generally more restrictive than the other licenses we use.
It'll greatly improve the experience for anyone wanting to work on the GCC backend from the compiler.
Should help with https://github.com/rust-lang/rust/issues/124172.
Will unblock #124353.

unify `llvm-bitcode-linker`, `wasm-component-ld` and llvm-tools logics
To use the precompiled `ci-rustc` in CI, we need to install `llvm-bitcode-linker` and LLVM tools into ci-rustc's sysroot. Without them some CI pipelines may fail, as shown [here](https://github.com/rust-lang/rust/pull/122709#issuecomment-2334365988).

refactor merge base logic and fix `x fmt`
When remote upstream is not configured, using [get_git_modified_files](https://github.com/rust-lang/rust/blob/38e3a5771cefc9362976a605549f8b04d5707311/src/tools/build_helper/src/git.rs#L114) to find modified files fails because [get_rust_lang_rust_remote](https://github.com/rust-lang/rust/blob/38e3a5771cefc9362976a605549f8b04d5707311/src/tools/build_helper/src/git.rs#L46-L48) can not resolve "rust-lang/rust" from the git output. The changes in this PR makes bootstrap to find the latest bors commit, treating it as the "closest upstream commit" so that the change tracker logic can use it to find the diffs.
In addition, [skips formatting](https://github.com/rust-lang/rust/commit/e3924544832668a6e239153a90d3be2077fbdce4) if there are no modified files.

miri-test-libstd: add missing BOOTSTRAP_ARGS
Note sure if BOOTSTRAP_ARGS will make any difference here, but all the other x.py invocations have it and I did not *deliberately* leave it away when I added these, so... probably best to add them?
Also don't unnecessarily set BOOTSTRAP_SKIP_TARGET_SANITY while we are at it.

bump download-ci-llvm-stamp
This should trigger the download and extraction of the ci-llvm tarball, which should resolve https://github.com/rust-lang/rust/issues/130144.

use `download-ci-llvm=true` in the default compiler config
https://github.com/rust-lang/rust/commit/1ca2708e77ac735adc3824501667694b4f9c1303 made it so that the `src/llvm-project` submodule has to be checkout for `download-ci-llvm = "if-unchanged"` to know if the submodule has been changed, but that is not required, if the submodule hasn't been checkout it cannot have been modified.
~~This PR restore the previous behavior by only updating the submodule if it has already been checkout.~~
This PR makes `download-ci-llvm = true` check if CI llvm is available and make it the default for the compiler profile, as to prevent unnecessarily checking out `src/llvm-project` with `"if-unchanged"`.
