Improve type checker performance (#13094)
Browse files Browse the repository at this point in the history 
* conditional declare `TOKENIZER_MAPPING_NAMES` within a `if TYPE_CHECKING` block so that type checkers dont need to evaluate the RHS of the assignment.

this improves performance of the pylance/pyright type checkers

* Update src/transformers/models/auto/tokenization_auto.py

Co-authored-by: Sylvain Gugger <35901082+sgugger@users.noreply.github.com>

* adding missing import

* format
