Add tight scoping to nodes in the dependency graph

Based on issues identified in https://github.com/CycloneDX/cyclonedx-maven-plugin/issues/310 and which has been discussed at https://github.com/guacsec/guac/issues/594 along with a [Slack discussion.](https://cyclonedx.slack.com/archives/CVCKP34A2/p1678480722085369) on the topic, this enhancement will introduce tight scoping for nodes in the dependency graph. In doing so, CycloneDX will be able to represent components with differing dependency trees across different modules in the same BOM.
