Rollup merge of #135266 - kadiwa4:no_emsdk_update, r=Mark-Simulacrum

Remove emsdk version update from 1.84.0 relnotes

See [this comment](https://github.com/rust-lang/rust/issues/131467#issuecomment-2529314603). The reproducer in that comment does indeed show that rustup's `rust-std` component is still compiled with the old emscripten ABI because libc's config flag `emscripten_new_stat_abi` is not set.

#131533 presumably had no effect because the wrong CI file was modified. So nothing has changed since 1.83.0. The PR author (workingjubilee) is currently on vacation.
Also the issue #131467 should be reopened.

- Support for the target named `wasm32-wasi` has been removed as the target is now named `wasm32-wasip1`. This completes the [transition](https://github.com/rust-lang/compiler-team/issues/607) [plan](https://github.com/rust-lang/compiler-team/issues/695) for this target following [the introduction of `wasm32-wasip1`](https://github.com/rust-lang/rust/pull/120468) in Rust 1.78. Compiler warnings on [use of `wasm32-wasi`](https://github.com/rust-lang/rust/pull/126662) introduced in Rust 1.81 are now gone as well as the target is removed.
- [The syntax `&pin (mut|const) T` is now parsed as a type which in theory could affect macro expansion results in some edge cases](https://github.com/rust-lang/rust/pull/130635#issuecomment-2375462821)
- [Legacy syntax for calling `std::arch` functions is no longer permitted to declare items or bodies (such as closures, inline consts, or async blocks).](https://github.com/rust-lang/rust/pull/130443#issuecomment-2445678945)
- The `wasm32-unknown-emscripten` target's binary release of the standard library is now [built with the latest emsdk 3.1.68](https://github.com/rust-lang/rust/pull/131533), which fixes an ABI-incompatibility with Emscripten >= 3.1.42. If you are locally using a version of emsdk with an incompatible ABI (e.g. before 3.1.42 or a future one), you should build your code with `-Zbuild-std` to ensure that `std` uses the correct ABI.
- [Declaring functions with a calling convention not supported on the current target now triggers a hard error](https://github.com/rust-lang/rust/pull/129935)
- [The next-generation trait solver is now enabled for coherence, fixing multiple soundness issues](https://github.com/rust-lang/rust/pull/130654)
