All of the providers in a module get compiled into a module definition in the
factory file. Some of these providers are for the actual module types, as those
are available for injection in Angular. For tree-shakeable tokens, the runtime
needs to be able to distinguish which modules are present in an injector.
This change adds a NodeFlag which tags those module providers for later
identification.

on @angular/core.
This add a duplication of some interfaces and enums which is stored
in @angular/compiler/src/core.ts
BREAKING CHANGE:
- `@angular/platform-server` now additionally depends on
`@angular/platform-browser-dynamic` as a peer dependency.
