Andrew Kushnir 0a1a989fa9 perf(core): avoid recursive scope recalculation when TestBed.overrideModule is used (#35454)
Currently if TestBed detects that TestBed.overrideModule was used for module X, transitive scopes are recalculated recursively for all modules that X imports and previously calculated data (stored in cache) is ignored. This behavior was introduced in https://github.com/angular/angular/pull/33787 to fix stale transitive scopes issue (cache was not updated if module overrides are present).

The perf issue comes from a "diamond" problem, where module X is overridden which imports modules A and B, which both import module C. Under previous logic, module C gets its transitive deps recomputed multiple times, during the recompute for both A and B. For deep graphs and big common/shared modules this can be super costly.

This commit updates the logic to recalculate ransitive scopes for the overridden module, while keeping previously calculated scopes of other modules untouched.
