HHH-10279 - Memory usage improvements -
* Don't allocate IdentityMap if it is not needed * Only allocate unresolved insertions if requied * Don't create a new string when creating a named query * Allocate querySpaces lazily * Remove executableLists from ActionQueue * Allocate ExecutableList instances lazily * Lazily allocate the transaction commit task lists * Don't allocate a new EntityKey
