Make the wasm_c_abi future compat warning a hard error

This is the next step in getting rid of the broken C abi for wasm32-unknown-unknown.

The lint was made deny-by-default in https://github.com/rust-lang/rust/pull/129534 3 months ago. This still keeps the `-Zwasm-c-abi` flag set to `legacy` by default. It will be flipped in a future PR.
