dbus/debugd: Add method for org.chromium.debugd.GetPerfOutput

This method will replace org.chromium.debug.GetRandomPerfOutput.
Unfortunately, the C++ method name "GetPerfOutput" was used for
the DBus method name "GetRandomPerfOutput", which means the most
appropriate name is taken. Since the DBus method "GetPerfOutput" will
soon be removed, I've overloaded the C++ method "GetPerfOutput" to call the
DBus method "GetPerfOutput". The difference betweeen these two methods
is that the new one takes a vector<string> containing the perf arguments
to call, whereas the old one makes a random selection of perf arguments.

The two methods have the same output type, and so share the
OnGetPerfOutput callback, and the GetPerfOutputCallback type.
