[wasm-split] Add an --asyncify option (#4513)
Add an option for running the asyncify transformation on the primary module
emitted by wasm-split. The idea is that the placeholder functions should be able
to unwind the stack while the secondary module is asynchronously loaded, then
once the placeholder functions have been patched out by the secondary module the
stack should be rewound and end up in the correct secondary function.
