What does this PR do?
This PR cleans up some code of ViT, BEiT, DeiT and DPT.
Most importantly, it corrects the tuple outputs, in case no pooler was added (as shown by #16760).
Next to that, it cleans up the tests, by
to_2tuple
, and instead leveraging anexpected_seq_len
attribute of theModelTester
chunk_length
andis_encoder_decoder
statements, which don't apply for these encoder-only models.
