Add Fast Segformer Processor (#37024)
* Add Fast Segformer Processor * Modified the params according to segformer model * modified test_image_processing_Segformer_fast args - removed redundant params like do_center_crop,center_crop which aren't present in the original segformer class * added segmentation_maps processing logic form the slow segformer processing module with references from beitimageprocessing fast * fixed code_quality * added recommended fixes and tests to make sure everything processess smoothly * Fixed SegmentationMapsLogic - modified the preprocessing of segmentation maps to use tensors - added batch support * fixed some mismatched files * modified the tolerance for tests * use modular * fix ci --------- Co-authored-by: yonigozlan <yoni.gozlan@huggingface.co>
