Link `std` statically in `rustc_driver`
This makes `rustc_driver` statically link to `std`. This is done by not passing `-C prefer-dynamic` when building `rustc_driver`. However building `rustc-main` won't work currently as it tries to dynamically link to both `rustc_driver` and `std` resulting in a crate graph with `std` duplicated. To fix that new command line option `-Z prefer_deps_of_dynamic` is added which prevents linking to a dylib if there's a static variant of it already statically linked into another dylib dependency.
The main motivation for this change is to enable `#[global_allocator]` to be used in `rustc_driver` allowing overriding the allocator used in rustc on all platforms.
---
Instead of adding `-Z prefer_deps_of_dynamic`, this PR is changed to crate opt-in to the linking change via the `rustc_private` feature instead, as that would be typically needed to link to `rustc_driver` anyway.

Promote aarch64-apple-darwin to Tier 1
This promotes aarch64-apple-darwin to Tier 1 status as per rust-lang/rfcs#3671 and tracking issue #73908. Not sure what else is necessary for this to impement the aforementioned RFC, however I figured I'd try. I did read in previous issues and PRs that the necessary infrastructure was already in place for the aarch64-apple-darwin target, and the RFC mentions the same. So this should be all thats necessary in order for the target to be promoted.
This is a recreation of my previous PR because I accidentally did an incorrect git rebase which caused unnecessary changes to various commit SHAs. So this PR is a recreation of my previous PR without said stumble. My bad.
[rustdoc] Stop showing impl items for negative impls
Fixes https://github.com/rust-lang/rust/issues/128799.
As discussed with `@fmease,` they have a broader patch in progress, so this (small) PR will at least allow for them to have a regression test. :)

Enable zstd for debug compression.
Set LLVM_ENABLE_ZSTD alongside LLVM_ENABLE_ZLIB so that --compress-debug-sections=zstd is an option.

Subtree sync for rustc_codegen_cranelift
The main highlight this time is support for raw-dylib on Windows thanks to `@dpaoliello.` Compiling the ring crate for arm64 macOS has been fixed too.

Disable verbose bootstrap command failure logging by default
One of my recent bootstrap command refactoring PRs enabled verbose logging of command failures by default. While this is great for debugging bootstrap, in many situations it's just too verbose and prevents the user from seeing the actual printed stdout/stderr, which usually contains much more useful information.
This PR reverts that logic, and only prints a detailed error when `-v` is passed to bootstrap.

add `builder-config` into tarball sources
This will be useful for certain scenarios where developers want to know how the tarball sources were generated. We also want this to check for CI rustc incompatible options on bootstrap.

VxWorks code refactored
1. Extern TaskNameSet as minimum supported version of os is VxWorks 7 which would have taskNameSet
2. Vx_TASK_NAME_LEN is 31 on VxWorks7, defined variable res.
3. Add unsafe blocks on Non::Zero usage in available_parallelism()
4. Update vxworks docs.

Set LLVM_ENABLE_ZSTD alongside LLVM_ENABLE_ZLIB so that --compress-debug-sections=zstd is an option.
Use static linking to avoid a new runtime dependency. Add an llvm.libzstd bootstrap option for LLVM
with zstd. Set it off by default except for the dist builder. Handle llvm-config --system-libs output
that contains static libraries.
Miscellaneous improvements to struct tail normalization
1. Make checks for foreign tails more accurate by normalizing the struct tail. I didn't write a test for this one.
2. Normalize when computing struct tail for `offset_of` for slice/str. This fixes the new solver only.
3. Normalizing when computing tails for disaligned reference check. This fixes both solvers.

Fuchsia Test Runner: enable ffx repository server
The default repository server setting has changed on Fuchsia (default is newly "false"). Now, in order to start the repository server, the config `repository.server.enabled` must be set to true.

Change generate-copyright to generate HTML, with cargo dependencies included
`x.py run generate-copyright` now produces `build/COPYRIGHT.html`. This includes a new format for in-tree dependencies, and also adds out-of-tree cargo dependencies.
After consulting expert opinion, I have elected to include every top-level:
* `*NOTICE*`
* `*AUTHOR*`
* `*LICENSE*`
* `*LICENCE*`, and
* `*COPYRIGHT*` file I can find - case-insensitive.
This is because the cargo package metadata's `author` field is not a list of copyright holders and does not meet the requirements of the Apache-2.0 license (which says you must include a NOTICE file with the binary if one was supplied by the author) nor the MIT license (which says you must include 'the above copyright notice').
I believe it would be appropriate to include this file with every Rust release, in order to do an even better job of appropriately recognising the efforts of the authors of the first-party and third-party libraries we are using here.
The output includes something like 524 copies of the Apache-2.0 text because they are not all identical. I think I count about 50 different variations by shasum - some differ in whitespace, while some have the boilerplate block at the bottom erroneously modified (don't modify the copy in the license, modify the copy you paste into your own source code!). Running `gzip` on the HTML file largely makes this problem go away, and the average browser is far happier with a ~6 MiB HTML file than the average Markdown viewer is with a ~6 MiB markdown file. But, if someone wants to, do they could submit a follow-up which de-dups the license text files and adds back-links to earlier identical copies (for some value of 'identical copy').
```console
$ xpy run generate-copyright
$ cd build
$ gzip -c COPYRIGHT.html > COPYRIGHT.gz
$ xz -c COPYRIGHT.html > COPYRIGHT.xz
$ ls -lh COPYRIGHT.*
