Remove dead post-hoc rehash check

Hash#rehash checks whether the hash is iterating, and with VWA,
RHASH_ST_TABLE() always returns the same thing for the same
hash.

RHASH_ST_TABLE(VALUE h)
{
    return (st_table *)((uintptr_t)h + sizeof(struct RHash));...

Remove rehash checking TODO (GH-13919)

Hash#rehash checks for rehash during iteration, and there
seems to be no efficient way to check for it after the fact,
so remove the TODO.

Fix size assertion in concurrent set resizing

Since we resize when prev_size > set->capacity / 2, it's possible that
prev_size == set->capacity / 2, so we need to change the assertion in
concurrent_set_try_resize_without_locking to be
new_set->size <= new_set->capacity / 2.
