QWasmSuspendResumeControl manages transfer of control from
JS to the wasm instance, when the wasm instance is asyncify
suspended.
Supported use cases include registerEventHandler()-type
event handlers, and also JS APIs which take a callback
functions, such as timers and requrestAnimationFrame.
The specific use cases are handled by adapters (not included
in this commit), which call the QWasmSuspendResumeControl API to
register JS/C++ event handler pairs:
uint32_t index = control->registerEventHandler([](val){ ... });
val jsHandler = control->jsEventHandler(index);
The C++ handler contains the user code, while the JS handler
can be passed to registerEventHandler or be used as a callback.
