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 .

They may contain pointers to themselves, such as when using
PODArrayWithStackMemory. Instead, initialize empty new structures

Fix initial size of some inline PODArray's.
...
A template parameter of PODArray named INITIAL_SIZE didn't make its
units clear, which made some callers to erroneously assume that it
specifies the number of elements and not the number of bytes.
Rename it, fix the wrong usages and, where possible, use the
PODArrayWithStackMemory typedef for arrays with inline memory.
