Ignore unknown methods in IDisplayWindowListener

New Android versions may add methods to IDisplayWindowListener.aidl.
When these methods are called by the system, they result in an
AbstractMethodError because they are not implemented on the scrcpy side.

To avoid releasing a new version for each newly added method, ignore
them at the Binder level.
