This PR adds support for package.json based secondary entry points and
implements fix for situation when package imports base entry point as
dynamic dependency and secondary entry point as static dependency.
## Current Behavior
When the package is imported from itself, check for a secondary entry
point checks only Angular-style secondary entry points.
When package is importing from the same library as dynamic import from
root and static import from secondary entry point we still get linter
errror.
## Expected Behavior
Check for secondary entry points should also support standard
package.json-based entry points.
Importing from the same library as dynamic import from root and static
import from secondary entry point should be allowed.

## Current Behavior
<!-- This is the behavior we have today -->
We only ever discover one version of an external dependency for the
file-map.json. This means the `@nx/dependency-checks` lint rule can
produce incorrect failures when multiple copies of a dependency exist
within a workspace.
## Expected Behavior
<!-- This is the behavior we should expect with the changes in this PR
-->
In the file-map.json the project specific version of a package (if
multiple exist) is preferred and therefore the lint rule produces
accurate results.

For example, in a repo where the root package.json has lodash@4.0.0
(which becomes `npm:lodash` on graph) and the foo project has
lodash@3.0.0:
