Non-obsoletion warnings as errors in Release. (#42983)

* Non-obsoletion warnings as errors in Release.

* Add two other obsoletions related to collection expressions.
These are not present in the codebase, but may become so in the future.

* Exempt NU1903 so the project can't mysteriously stop building.

* Fix some FULL_RELEASE mistakes.

* diff fix

* Resharper caught this one. Note to self: Wire up resharper to CI in another PR.
