worker: improve MessagePort performance
Use a JS function as the single entry point for emitting `.onmessage()`
calls, avoiding the overhead of manually constructing each message
event object in C++.
confidence improvement accuracy (*) (**) (***)
worker/echo.js n=100000 sendsPerBroadcast=1 payload='object' workers=1 *** 16.34 % ±1.16% ±1.54% ±1.99%

Also fix handling exceptions returned from `MessagePort::New`.
