docs(test_lib/test_injector): fix invalid jsdoc type

chore(doc-gen): capture docs for modules from comments

Closes #1258

docs(*): add module description jsdoc tags
docs(*): add @public tag to public modules
chore(doc-gen): fix overview-dump template
The template was referencing an invalid property
chore(doc-gen): use `@exportedAs` and `@public` rather than `@publicModule`

This commit refactors how we describe components that are re-exported in another
module. For example the "public" modules like `angular/angular` and `angular/annotations`
are public but they only re-export components from "private" modules.

Previously, you must apply the `@publicModule` tag to a component that was to be
re-exported. Applying this tag caused the destination module to become public.

Now, you specify that a module is public by applying the `@public` tag and then
you can "re-export" components to other modules by applying the `@exportedAs`
giving the name of the module from which the component will be re-exported.
tag. This tag can be used multiple times on a single component, allowing the
component to be exported on multiple modules.

docs(*): rename `@publicModule` to `@exportedAs`

The `@publicModule` dgeni tag has been replaced by the `@exportedAs`
dgeni tag on components that are to be re-exported on another module.
