Make the quadratic Arena::allocContinue less bad.
...
Scenarios that use Arena::allocContinue may waste quadratically many
memory and perform quadratically many copying, when the memory range
size reaches Arena's linear allocation threshold. To alleviate this,
make sure that the next memory chunk allocated by allocContinue is at
least linear_growth_threshold bytes bigger than the previous one, so
that we don't reallocate and copy that often.

Key memory management for compound hash tables.
...
Some aggregation methods initially emplace a temporary StringRef key
into a hash table. Then, if the key was not seen before, they make a
persistent copy of the key and update the hash table with it. This
approach is not suitable for compound hash tables, because the logic of
when the persistent key is needed is more complex, and is contained
within the hash table itself.
In this commit, we switch to managing key memory with callbacks passed
to the hash table, that allow it to request a persistent copy of the key
if it is needed. This should be more appropriate for compound hash
tables.
This commit prepares for StringHashMap PR #5417 .
