Which @angular/* package(s) are relevant/related to the feature request?

Description

With the popularity of standalone components (pipes/directives), powered by Angular as well, there is a possibility that some components will be unused in templates while still imported by parent component, and so will increase bundle

Proposed solution

Report during the build that some.pipe/directive is imported but not used.
It can be controlled via angulqrCompilerOptions of tsconfig
