[`module_name_repetition`] Recognize common prepositions

Fixes #12544

changelog: [`module_name_repetition`]: don't report an item name if it consists only of a prefix from `allowed-prefixes` list and a module name (e.g. `AsFoo` in module `foo`). Prefixes allowed by default: [`to`, `from`, `into`, `as`, `try_into`, `try_from`]
