Add @JavaPassthrough annotation

The AIDL annotation is used to pass Java annotation to the generated
java code. It is ignored in other backends like C++ and NDK.
Specifically, an AIDL method

@JavaPassthrough(annotation="@com.android.MyAnnotation")
void foo();

becomes a Java method

@com.android.MyAnnotation
void foo() extends RemoteException;

Note that the Java annotation syntax inside the "annotation" parameter
is not parsed. It's left to the Java compiler which will compile the
generated code.
