When type-checking a component, the declaring NgModule scope is used to create a directive matcher that contains flattened directive metadata, i.e. the metadata of a directive and its base classes. This computation is done for all components, whereas the type-check scope is constant per NgModule. Additionally, the flattening of metadata is constant per directive instance so doesn't necessarily have to be recomputed for each component. This commit introduces a `TypeCheckScopes` class that is responsible for flattening directives and computing the scope per NgModule. It caches the computed results as appropriate to avoid repeated computation. PR Close #38539
