Fix usage of additional kwargs in `from_encoder_decoder_pretrained` in...

Fix usage of additional kwargs in `from_encoder_decoder_pretrained` in encoder-decoder models (#15056)

* [EncoderDecoder] Add test for usage of extra kwargs

* [EncoderDecoder] Fix usage of extra kwargs in from pretrained

* [EncoderDecoder] apply suggested changes (passing **kwargs_encoder)

* [EncoderDecoder] create new test function and make sure it passes
