Support multiple QML engines in V4 debugger

Whenever the debugger is paused, there is exactly one engine that
caused the debuggerPaused() slot to be called. We can only interact
with that engine in any meaningful way.

Of course you can shoot yourself in the foot with this tool. You can,
for example, set a breakpoint that will be hit by multiple engines and
then get confused about which engine just hit the breakpoint. Similar
things are also possible with other kinds of debuggers, though. If this
becomes a problem we can add an engine ID to the responses.

Also, this does not fix the other debug services. So you might still
not see the "correct" locals and expressions from the
QQmlEngineDebugService while the debugger is not paused.
