Resolves a platform key to its concrete SQLDialect instance.
This is the single factory for platform dialect resolution — all consumers should
call this instead of maintaining their own switch/map. It serves the built-in platform
dialects and any full SQLDialect registered with the class factory; a query-only
dialect (see GetQueryDialect) is refused.
