1. sys: use process::abort() instead of arch::wasm32::unreachable() …

   Rationale:
   
     - `abort()` lowers to `wasm32::unreachable()` anyway.
     - `abort()` isn't `unsafe`.
     - `abort()` matches the comment better.
     - `abort()` avoids confusion by future readers (e.g.
       rust-lang#81527): the naming of wasm's
       `unreachable' instruction is a bit unfortunate because it is not
       related to the `unreachable()` intrinsic (intended to trigger UB).
   
   Codegen is likely to be different since `unreachable()` is `inline`
   while `abort()` is `cold`. Since it doesn't look like we are expecting
   here to trigger this case, the latter seems better anyway.
