erts: Redesign grow/shrink thresholds of hash.c
1. Use load factor as indicator, not used buckets.
Used buckets is a bad indicator as it makes the situation even
worse with a bad hash function.
Set grow_threshold to load factor of 160% as it roughly corresponds
to the old 80% used bucket limit.
2. Never shrink table below initial size.
