Build the Maven dependency tree with Maven Resolver instead of maven-dependency-tree

DependencyTreeFactory now collects the project graph with the Maven Resolver
conflict resolver in verbose mode and returns a NetBeans-owned DependencyNode,
so the unmaintained maven-dependency-tree 2.2 jar and its friend packages go.

+                now builds the tree from Maven Resolver's verbose dependency graph and returns the new
+                <code>org.netbeans.modules.maven.embedder.tree.DependencyNode</code>, which offers the subset of the
+                former API that NetBeans used. The Maven Dependency Tree library is no longer bundled, and the
+                <code>org.apache.maven.shared.dependency.*</code> packages are no longer exported to friends.
+                Update imports to the new package; use the Maven Resolver API directly where the dependency graph is needed.
