Disable regex caching in tests

[brandonwillard]

Describe the issue as clearly as possible:

Tests like test_regex_vocabulary_error can fail due to the caching of create_states_mapping.

Caching should probably be disabled somewhat generally in those test modules (except for tests that are specifically for caching, of course).

Steps/code to reproduce the bug:

NA

Expected result:

NA

Error message:

No response

Outlines/Python version information:

Context for the issue:

There's no need for that; we shouldn't be caching the operations we're testing when we aren't testing the caching itself.

Yep, the PR disables caching on everything except tests.test_cache and tests.benchmark (benchmarks have their own cache handling)
