476ba679 - Feature to use the PreTrainedTokenizerFast class as a stand-alone tokenizer (#11810)

Feature to use the PreTrainedTokenizerFast class as a stand-alone tokenizer (#11810) * feature for tokenizer without slow/legacy version * format * modify common test * add tests * add PreTrainedTokenizerFast to AutoTokenizer * format * change tokenizer common test in order to be able to run test without a slow version * update tokenizer fast test in order to use `rust_tokenizer_class` attribute instead of `tokenizer_class` * add autokenizer test * replace `if self.tokenizer_class is not None` with ` if self.tokenizer_class is None` * remove obsolete change in comment * Update src/transformers/tokenization_utils_base.py Co-authored-by: Lysandre Debut <lysandre@huggingface.co> * Update src/transformers/tokenization_utils_fast.py Co-authored-by: Sylvain Gugger <35901082+sgugger@users.noreply.github.com> * change `get_main_tokenizer` into `get_tokenizers` * clarify `get_tokenizers` method * homogenize with `test_slow_tokenizer` and `test_rust_tokenizer` * add `test_rust_tokenizer = False` to tokenizer which don't define a fast version * `test_rust_tokenizer = False` for BertJapaneseTokenizer * `test_rust_tokenizer = False` for BertJapaneseCharacterTokenizationTest Co-authored-by: Lysandre Debut <lysandre@huggingface.co> Co-authored-by: Sylvain Gugger <35901082+sgugger@users.noreply.github.com>
