Android: Support multi-arg signal generation in androiddeployqtHEADdev

This commit introduces support for generating Java code for
multi-argument QML signals.

Pre-existing code remains unchanged, and the new code is only executed
when the number of params in a signal is above 1.

Multi-arg signals are handled with a new generated interface type,
named after the signal, which has a default method that takes an
Object[] array and calls the user-implemented signal method with the
arguments cast to the desired types.

For example, a QML signal with the following signature:

signal manyTypeArgSignal(intValue: int, boolValue: bool,
doubleValue: double, stringValue: string)

Is generated into this Java code:

@FunctionalInterface
public interface manyTypeArgSignalListener {
    default void onSignalEmitted(Object[] args) {
        onSignalEmitted((Integer) args[0], (Boolean) args[1], (Double) args[2], (String) args[3]);
    }
    void onManyTypeArgSignal(Integer intValue, Boolean boolValue, Double doubleValue, String stringValue);
}
public int connectManyTypeArgSignalListener(manyTypeArgSignalListener signalListener) {
    return connectSignalListener("manyTypeArgSignal", new Class[]{ Integer.class, Boolean.class, Double.class, String.class }, signalListener);
}
