HHH-14153 optimize away temp table for single-table HQL update
When a HQL bulk update query only touches a single table,
use BasicExecutor instead of MultiTableUpdateExecutor.
This is an alternate implementation to the one proposed by
@NathanQingyangXu in #3508 and loosely based on that work.

HHH-14153 further optimization for single-table HQL update
This extends the optimization for single-table HQL bulk
updates to the case where the where clause touches multiple
tables and we can use a subselect to collect the ids that
we need to update.

HHH-14153 refactoring after HHH-14153
- avoid use package-scoped instance felds
- remove copy/pasted code
Note: I don't hate package-scoped final fields, but I
know other folks tend to. So let's go with template
methods instead.
