d1f1633c60 refactor: Remove wal_checkpoint_mutex, lock write_mutex before getting sql connection instead
The original idea was to always lock `write_mutex` before acquiring an `InnerPool.semaphore` permit
to avoid ABBA deadlocks, but when refactoring a PR for b696a242fc,
that was forgotten.

This doesn't really change the program flow as we have `Context::housekeeping_mutex` anyway,
just simplifies the code.

874e38c146 refactor: move WAL checkpointing into sql::pool submodule
This change is mainly to avoid exposing the write lock outside the pool module.
To avoid deadlocks, outside code should work only with the pooled connections
and use no more than one connection per thread.
