fix(core): call ngOnDestroy for tree-shakeable providers (#28943)

Prior to this change, any provider that was independently resolved using
its InjectableDef would not be considered when destroying the module it
was requested from. This commit provides a fix for this issue by storing
the resolved provider in the module's list of provider definitions.

Fixes #28927
