Morten Sørvig f347682fd5 wasm: include asyncify support unconditionally
Emscripten's option for enabling asyncify (-sASYNCIFY) is a link-time
option, which means there is no requirement to have a separate asyncify
build, at least for static builds.

Replace the current QT_HAVE_EMSCRIPTEN_ASYNCIFY compile-time option
with a run-time option which checks if the asyncify API is available.

Keep support for configuring with "-device-option QT_EMSCRIPTEN_ASYNCIFY=1"
for backwards compatibility and for the use case where want asyncify
support to be on by default for a given Qt build.

Enable asyncify for the asyncify_exec example.

Pick-to: 6.4

Event loop exec() and main() on Qt for WebAssembly

These examples demonstrate how QEventLoop::exec() works on Qt for WebAssembly, and also shows how to implement main() without calling QApplication::exec().

Contents

main_exec       Standard Qt main(), where QApplication::exec() does not return
main_noexec     Qt main() without QApplication::exec()
dialog_exec     Shows how QDialog::exec() also does not return
thread_exec     Shows how to use QThread::exec()
eventloop_auto  Event loop autotest (manually run)
