Unified Build control update

[mmitche]

Description

This issue is dependent on dotnet/source-build#2974 and is a placeholder for .NET 8 required work in product repositories.

Instructions for implementation will be updated once dotnet/source-build#2974 but will likely be a mechanical shift of properties in this repo. In a general sense, this is scaffolding work for expanding the set of source-built platforms beyond Linux.

Marked this as blocked for now given we have no much context about the work.

@mmitche does this still need to be open?
