ecdf95c6 - fix: add identity reverse_op to dequantize ops for save_pretrained (#44983)

fix: add identity reverse_op to dequantize ops for save_pretrained (#44983) fix: add identity reverse_op to dequantize operations for save_pretrained Dequantize operations (Mxfp4Dequantize, Fp8Dequantize, MetalDequantize) raise NotImplementedError on reverse_op, causing save_pretrained to fail for models loaded with dequantize=True. Add _IdentityOp as the reverse_op so dequantized weights are saved as-is.
