c7ec5a13a5 remove locks from AtomTable
there are technically still two locks
- the Mutex to serialize consurrent updates to the AtomTable
- the RwLock as part of GLOBAL_ATOM_TABLE

the former is the age lock of RESIZE ATOM TABLE in <https://arxiv.org/pdf/1608.00989.pdf>, though we use it for the whole update as we don't match the whole structure and can't reserve an atom slot as is, so we need to also lock concurrent updates without resizing

the later should be uncontendet as we only write AtomTable::new iff the current value is a dangling Weak

4ef8c5c47d detect and prevent² concurrent AtomTable use
²in the case of `#[cfg(not(test))]` there is still a toctou race as I am not sufficently familiar with Atomics
