Prepare for strict coherency (#23227)

* Prepare for strict coherency
Strict coherency means that if your repo declares a dependency with a CPD attribute, the CPD parent must have a direct dependency on that dependency.
This means for aspnetcore that it should add a dependency on System.Resources.Extensions because aspnetcore-tooling needs it.

Reasons for this approach over the current approach:
- This eliminates some ambiguous tie-breaking scenarios that are very problematic and dangerous in servicing
- Those tie breaking scenarios require the use of BAR to break the ties. If the DB data were to be lost then the tie-breaking would do unexpected things.
