Listing the dependants of a component

### Current Behavior

Given a component, currently if you want to extract the list of dependants of that component the only thing you can do (from the UI) is scrolling the Dependency Graph, which can be very hard when you have too many components.

### Proposed Behavior

Inside each component tab, adding a "Dependants" tab which lists all the components that depend on the selected component. In addition there should be a toggle button to filter only the project's direct dependencies (similarly to what you can do under Project > Components).

This would be useful when, given a vulnerable component, you need to extract the list of direct component to update in order to fix the vulnerable component.
