[wasm] Block compile/instantiate of large array buffers

[wasm] Block compile/instantiate of large array buffers

To discourage development patterns leading to bad user experience, we
block wasm compilation/instantiation through the sync APIs
for modules larger than a certain size.

Promise-based APIs still succeed; also, sync APIs succeed in worker
contexts.
