This is a tracking issue for the MCP "perma-unstable wasm-c-abi flag" (rust-lang/compiler-team#703).

About tracking issues

Tracking issues are used to record the overall progress of implementation.
They are also used as hubs connecting to other relevant issues, e.g., bugs or open design questions.
A tracking issue is however not meant for large scale discussion, questions, or bug reports about a feature.
Instead, open a dedicated issue for the specific matter and add the relevant feature gate label.

Introduce perma-unstable `wasm-c-abi` flag

Now that `wasm-bindgen` v0.2.88 supports the spec-compliant C ABI, the idea is to switch to that in a future version of Rust. In the meantime it would be good to let people test and play around with it.

This PR introduces a new perma-unstable `-Zwasm-c-abi` compiler flag, which switches to the new spec-compliant C ABI when targeting `wasm32-unknown-unknown`.

Alternatively, we could also stabilize this and then deprecate it when we switch. I will leave this to the Rust maintainers to decide.

This is a companion PR to rust-lang#117918, but they could be merged independently.

Since 1.78 a future-compat-warning for using too-old versions of wasm-bindgen has been in place, and now 75% of the ecosystem's downloads of crates are wasm-bindgen 0.2.89 or higher. I have opened #129534 as a discussion point for whether we should move the warning to a deny.

wasm: Depend on wasm-bindgen 0.2.89 or higher (#497)
aa13fa5 
wasm-bindgen 0.2.62 is not compatible with a wasm ABI change that rustc
wishes to enable by default for wasm32-unknown-unknown, currently gated
behind passing the -Zwasm-c-abi flag to rustc.

wasm-bindgen 0.2.89 should exhibit seamless behavior before and after
the ABI change to match the C ABI, so depend on that.
