Add new endpoint for DependencyGraph

[sahibamittal]

Description

In this PR I create two new endpoints GET /api/v1/dependencyGraph/project/{uuid}/directDependencies and
GET /api/v1/dependencyGraph/component/{uuid}/directDependencies.

The purpose of this endpoint it's to avoid the frontend from doing multiple requests to the backend to fetch each node of the Dependency Graph. With this endpoint, you can get all directDependencies of a project or a component by providing his UUID.

Ports DependencyTrack/dependency-track#3083 and DependencyTrack/dependency-track#2623.

Addressed Issue

DependencyTrack/hyades#858
