JoostK 8317042483 perf(core): do not recurse into modules that have already been registered (#39514)
When registering an NgModule based on its id, all transitively imported
NgModules are also registered. This commit introduces a visited set to
avoid traversing into NgModules that are reachable from multiple import
paths multiple times.

Fixes #39487
