Determine if the scope of the function to be serialized includes asm-
wasm, and if so, bypass serialization, since we do not support it in
that scenario.
In this change, we do so regardless of whether the asm-wasm path was
successful. This is so we keep the design simple, since the guidance
to developers, moving forward, is to use wasm.
