Compatibility shims for BART tokenizers in v5.

In v5 we consolidate on the tokenizers-library backend and remove separate
"slow" vs "fast" implementations. BART uses the same byte-level BPE
tokenizer as RoBERTa, so we expose `BartTokenizer` and `BartTokenizerFast`
as aliases to `RobertaTokenizer` to preserve the public API expected by
existing code and tests.

from ..roberta.tokenization_roberta import RobertaTokenizer as _RobertaTokenizer


# Public aliases maintained for backwards compatibility
BartTokenizer = _RobertaTokenizer
BartTokenizerFast = _RobertaTokenizer
