Search by dependencies

[Chriscbr]

As a user, I would like to be able to search for construct libraries that have a particular dependency, such as @aws-cdk/aws-ec2.

This could require a different search mechanism since the current search we have available is limited to the information in catalog.json, which does not contain package dependency information.
