Add flags to support easy disablement of SB prebuilt checking

[MichaelSimons]

Related to dotnet/source-build#5034

Setting SetUpSourceBuildIntermediateNupkgCache=false will disable the intermediate restoration and setting
ReportPrebuiltUsage=false will disable the prebuilt validation. Both will be necessary to set during the flat flow enablement.

SetUpSourceBuildIntermediateNupkgCache was previously unused so I repurposed it.

For targets in SourceBuild/SourceBuildArcadeTools.targets to run, SetUpSourceBuildIntermediateNupkgCache should not be false. Would it make sense to skip this import in that case?

[MichaelSimons]

I decided against it. This is going away shortly all together once the flat flow is stabilized. The existing implementation felt odd in the sense that the import still happened in many scenarios where the targets were conditioned out.

@MichaelSimons does this need to be backported to release/9.0 for repositories that use the 9.0 Arcade SDK? cc @premun @akoeplinger

[MichaelSimons]

No, we do not want to disable prebuilt detection for repos flowing into 9.0.

[ViktorHofer]

Right. How should we handle repositories that use 9.0 Arcade but consume 10.0 SB intermediate packages? Example: https://github.com/dotnet/razor/blob/4ed93db9c39d970197c3410f9e878caaf8a92316/eng/Version.Details.xml#L8-L13

I see this commit is from main. Will main flow into a 9.0 sdk feature band? If so it really should be on a 9.0 SBRP version. If it doesn't flow to 9.0, then why isn't it on 10.0 arcade?

I have no specific concern with backporting this, but we should not be disabling prebuilt detection on repos flowing into 9.0. Aside from disabling prebuilt detection, this will cause a ripple effect on other 9.0 repos that depend on it's intermediates.

SBRP 10.0 with a 9.0 Arcade seems to be a pattern:

• https://github.com/dotnet/razor/blob/4ed93db9c39d970197c3410f9e878caaf8a92316/eng/Version.Details.xml#L8-L13
• https://github.com/dotnet/roslyn/blob/4b30be27dfe5d37a605327d832c6c21468e246c2/eng/Version.Details.xml#L16-L20
• https://github.com/microsoft/vstest/blob/7b36464c47dbe0bd968972b3470e6e9da38209f2/eng/Version.Details.xml#L24-L29

SBRP 10.0 with a 9.0 Arcade seems to be a pattern:

Discussed offline. Those are incorrect and should be on 9.0. @ViktorHofer is updating the subscriptions.

[ViktorHofer]

OK only those three repos - puuuh
