Enable source-build pre-built detection

Part of dotnet/source-build#3017

Enable source-build pre-build detection on the current repository and resolve any pre-build issues discovered

[oleksandr-didyk]

As part of work on the task we discovered that in the context of repo build msbuild's source-build is utilizing older versions of several components (for example, 7.0 and 6.0 versions of system libraries). In the context of current product source-build, these dependencies will be replaced by their respective latest versions. This creates a sizable difference in behaviour between the product source-build and the repo source-build.

@rainersigwald pinging you here to get an opinion on what, in your mind, is a better option from msbuild's perspective -> to have source-build continue using the latest versions (i.e. source-build differs from 'VS build') or for source-build to use the VS-compatible ones (i.e. source-build behaves the same as 'VS build')? The later will become possible with the introduction of repository ProjectVersions.props files.

I thought we had no choice but the former. For .NET SDK scenarios we have no problem with the idea of using the latest everything--that's what we expect at runtime. For Visual Studio, we must move at the pace of Visual Studio and be on stable releases.

There's some risk of churn/annoyances with building against two different versions, but I'm willing to give it a try and complain if it becomes difficult.

Yeah, the issue wasn't linked to the resolving PR - #8678
