[wasm] Deprecate reachability tracking in SsaEnv Reachability is already being tracked in the function body decoder. This CL adds a DCHECK that the reachability tracked in the SsaEnv matches the reachability tracked in the function body decoder. Most of our methods will only be called for reachable code anyway. For exceptions, we still track reachability explicitly for now in the wasm graph builder, this can be refactored in the future by improving reachability tracking for catch blocks in the function body decoder. If this DCHECK survives fuzzing for a few days, we can remove code that handles unreachable code in graph-building-interface.cc.
