* add check and prepare args for BC to ProcessorMixin, improve ProcessorTesterMixin * change size and crop_size in processor kwargs tests to do_rescale and rescale_factor * remove unnecessary llava processor kwargs test overwrite * nit * change data_arg_name to input_name * Remove unnecessary test override * Remove unnecessary tests Paligemma * Move test_prepare_and_validate_optional_call_args to TesterMixin, add docstring
