Minimize the build graph by deleting unnecessary references (#68603)

* Minimize the build graph by deleting references Minimizing projects' dependency graph. There are tons of unnecessary Reference and ProjectReference items which aren't required anymore as the referenced projects became full facade assemblies. Removing those from a leaf's graph makes the graph smaller and therefore the project's evaluation and build faster. * Update src/libraries/System.Net.Quic/ref/System.Net.Quic.csproj Co-authored-by: Jeremy Barton <jbarton@microsoft.com> * Update Versions.props Co-authored-by: Jeremy Barton <jbarton@microsoft.com>
