Decouple WASIp2 sockets from WasiFd
This is a follow up to #129638, decoupling WASIp2's socket implementation from WASIp1's `WasiFd` as discussed with `@alexcrichton.`
Quite a few trait implementations in `std::os::fd` rely on the fact that there is an additional layer of abstraction between `Socket` and `OwnedFd`. I thus had to add a thin `WasiSocket` wrapper struct that just "forwards" to `OwnedFd`. Alternatively, I could have added a lot of conditional compilation to `std::os::fd`, which feels even worse.
Since `WasiFd::sock_accept` is no longer accessible from `TcpListener` and since WASIp2 has proper support for accepting sockets through `Socket::accept`, the `std::os::wasi::net` module has been removed from WASIp2, which only contains a single `TcpListenerExt` trait with a `sock_accept` method as well as an implementation for `TcpListener`. Let me know if this is an acceptable solution.

Reserve guarded string literals (RFC 3593)
Implementation for RFC 3593, including:
- lexer / parser changes
- diagnostics
- migration lint
- tests
We reserve `#"`, `##"`, `###"`, `####`, and any other string of four or more repeated `#`. This avoids infinite lookahead in the lexer, though we still use infinite lookahead in the parser to provide better forward compatibility diagnostics.
This PR does not implement any special lexing of the string internals:
- strings preceded by one or more `#` are denied
- regardless of the number of trailing `#`
- string contents are lexed as if it was just a bare `"string"`
Tracking issue: #123735
RFC: rust-lang/rfcs#3593
Ignore broken-pipe-no-ice on apple (specifically macOS) for now
This test fails for me locally (initially reported by Zalathar) because apparently on macOS it doesn't say "internal compiler error" but it does report the std I/O panic, and it doesn't exit with a code of 101 but instead terminates with a wait signal of SIGPIPE.
Ignore this test on apple for now, until we try to actually address the underlying issue.
See https://github.com/rust-lang/rust/pull/131155 and https://github.com/rust-lang/rust/issues/131436 for more context.
Fix quotation marks around debug line in `src/ci/run.sh`
Without this change, the markdown-style backticks are treated as a shell
command substitution, which fails like so:
/checkout/src/ci/run.sh: line 58: DISABLE_CI_RUSTC_IF_INCOMPATIBLE: command not found
debug: configured.

compiler: Stop reexporting enum-globs from `rustc_target::abi`
Three enums had **all** their variants glob-exported into a distressingly large amount of the tree. Cease to do that, and also cease to glob import the contents of the module that contained them. Redirect relevant imports to their actual source, the `rustc_abi` crate.
No functional changes.
Dont ICE when encountering post-mono layout cycle error
It's possible to encounter post-mono layout cycle errors in `fn_abi_of_instance`. Don't ICE in those cases.
This was originally discovered in an async fn, but that's not the only way to encounter such an error (which the other test I added should demonstrate).
Error messsages suck, but this fix is purely about suppressing the ICE.
Fixes#131409
Add "reference" as a known compiletest header
This adds the "reference" compiletest header so that the Rust reference can add annotations to the test suite in order to link tests to individual rules in the reference.
Tooling in the reference repo will be responsible for collecting these annotations and linking to the tests.
More details are in MCP 783: https://github.com/rust-lang/compiler-team/issues/783
There is a change from the MCP in that I am not adding the JSON collection to compiletest (at least, not yet). In looking at this more closely, that actually makes things more difficult for our tooling, so I'm leaving it out for now. If in the future it looks like something we want, then I think we can add it later.
There are a few tests here which need adjusting due to the legacy header check. `@jieyouxu` indicated on Zulip that we could potentially remove the legacy header check, in which case those changes can be dropped from this PR.

Rename directive `needs-profiler-support` to `needs-profiler-runtime`
The rest of the compiler mostly refers to this as `profiler_runtime`, so having a directive named `needs-profiler-support` was causing a lot of confusion.

This also adds three license exceptions to Cargo.
* arrayref — BSD-2-Clause
* blake3 — CC0-1.0 OR Apache-2.0 OR Apache-2.0 WITH LLVM-exception
* constant_time_eq — CC0-1.0 OR MIT-0 OR Apache-2.0
These exceptions were added to rustc in rust-lang/rust#126930, so should be fine for Cargo as well.
