Migrate from `maven-dependency-tree` to direct use of Resolver API

[basil]

Tamás Cservenák recommends we get rid of org.apache.maven.shared.dependency.graph.DependencyGraphBuilder (maven-dependency-tree). While not officially deprecated (yet), this suffers from same issues as all other legacy/maven2 things (e.g., maven-artifact-transfer), (mis)uses project building request everywhere, uses deprecated classes (e.g., ArtifactRepository), etc.

The suggestion is to replace this with direct usages of the Resolver API. For examples:
