`ares_destroy()` race condition during shutdown due to missing lock (#831)

When using EventThreads, the config change cleanup code might manipulate
the event update list if it uses file descriptors (such as on Linux).
This was being done without a lock. Rework the event enqueuing to handle
locking internally to prevent this and to simplify where it is used.
This was found by chance during an ASAN CI run.
