Since #33844, eager loading/preloading with too many and/or too large
ids won't be broken by pre-checking whether the value is constructable
or not.

But the pre-checking caused the type to be evaluated at relation build
time instead of at the query execution time, that is breaking an
expectation for some apps.

I've made the pre-cheking lazy as much as possible, that is no longer
happend at relation build time.
