Simplify thread synchronization in QQmlDebugServer

m_clientPlugins will only be accessed from the server thread, so it
doesn't need to be protected by a mutex. m_plugins will only be
modified before the server thread starts and after it ends. During the
runtime of the thread it is constant and thus doesn't need to be
protected, either.

Engines are supposed to be added and removed after any waiting for
connections and hello messages is done, so we can reuse the hello mutex
for synchronization there.
