Add support for Arm64EC to the Standard Library
Adds the final pieces so that the standard library can be built for arm64ec-pc-windows-msvc (initially added in #119199)
* Bumps `windows-sys` to 0.56.0, which adds support for Arm64EC.
* Correctly set the `isEC` parameter for LLVM's `writeArchive` function.
* Add `#![feature(asm_experimental_arch)]` to library crates where Arm64EC inline assembly is used, as it is currently unstable.
Render matched macro arm on hover of macro calls
Fixes https://github.com/rust-lang/rust-analyzer/issues/4028, its a different take on the idea. I don't like go to being changed here simply because we can't point the focus range on the name anymore as we usually do, and some editors might use this feature (and the focus range) for certain other things. We could instead add a new hover action for this to move to the arm directly (or maybe make `go to implementation` jump to the arm?)
Add CONTRIBUTING.md
I'm not great with these kinds of documents, but the main point I want to be able to raise is that feature implementations should have an issue raised first for discussion.
fix: VFS should not walk circular symlinks
As of #6246, rust-analyzer follows symlinks. This can introduce an infinite loop if symlinks point to parent directories.
Considering that #6246 was added in 2020 without many bug reports, this is clearly a rare occurrence. However, I am observing rust-analyzer hang on projects that have symlinks of the form:
```
test/a_symlink -> ../../
```
Ignore symlinks that only point to the parent directories, as this is more robust but still allows typical symlink usage patterns.
Move confusing comment about otherwise blocks in `lower_match_tree`
This comment was historically inside a block guarded by `if let Some(otherwise_block) = otherwise`.
When #120978 made the “otherwise block” non-optional, it also flattened that region of code. Doing so left this comment awkwardly stranded above an unrelated line of code, without its original context.
We can restore that context by moving it above the declaration of `otherwise`.

Fix copy path button
Currently, on all nightly docs, clicking on the "copy path" button triggers a JS error. It's because changes in https://github.com/rust-lang/rust/pull/123706 forgot to update the JS (it contained an image before but not anymore).
I had to make some small changes in the CSS to fix the display when the button was clicked as well.

crashes: add even more tests?!?
adds more tests that were not already added with https://github.com/rust-lang/rust/pull/124038 from the past 10 months or so.
Need a couple more passes through the tracker to filter out more missing ice /fixed tests but we're slowly getting there.
Delay interning errors to after validation
fixes https://github.com/rust-lang/rust/issues/122398fixes#122548
This improves diagnostics since validation errors are usually more helpful compared with interning errors that just make broad statements about the entire constant

Update how WASI toolchains are used in CI and bootstrap
This commit updates how the WASI targets are configured with their toolchain. Long ago a `config.toml` option of `wasi-root` was added to enable building with the WASI files produced by wasi-libc. Additionally for CI testing and release building the Rust toolchain has been using a hard-coded commit of wasi-libc which is bundled with the release of the `wasm32-wasip1` target, for example.
Nowadays though the wasi-sdk project, the C/C++ toolchain for WASI, is the go-to solution for compiling/linking WASI code and contains the more-or-less official releases of wasi-libc. This commit migrates CI to using wasi-sdk releases and additionally updates `bootstrap` to recognize when this is configured. This means that with `$WASI_SDK_PATH` configured there's no further configuration necessary to get a working build. Notably this also works better for the new targets of WASI as well, such as `wasm32-wasip2` and `wasm32-wasip1-threads` where the wasi-sdk release now has libraries for all targets bundled within it.
