Avoid an expensive call to toLocal8Bit upon thread creation

QString::toLocal8Bit() will need to call QTextCodec::codecForLocale(),
which isn't the cheapest of the functions, at least the first time it's
run. So avoid calling it when in most scenarios, the name of the QObject
isn't set, and the information is purely for debugging.

Additionally, avoid allocating memory when setting the thread name to
the class name. The class name coming from the meta object is a static
constant string and we can use it directly.
