wasm: implement stackProperties()
Implement stackProperties() for Q_OS_WASM using the
API provided by emscripten/stack.h, which is in practice
more reliable than pthread_attr_getstack().
This API returns the logical stack region, which can be
forwarded directly to createStackProperties().
Task-number: QTBUG-109942
Pick-to: 6.5
