Redesign comphelper::emscriptenthreading::Data::eventHandlerThread

Instead of being a thread that keeps blocking in C++
emscripten::ProxyingQueue::execute(), make it a thread that immediately goes
back to the browser event loop via emscripten_exit_with_live_runtime().  (Which
will eventually allow setupMainChannel from desktop/source/app/appinit.cxx to
run on that thread and receive the "LOWA-channel" JS message event.)

The thread is detached now and no longer joined in
comphelper::emscriptenthreading::tearDown, but that was mostly academic anyway
(as LOWA doesn't terminate in the traditional sense, and just stops when you
close its browser tab).
