SourceBuild leg is not using source-built arcade

[ericstj]

We discovered in #66144 that our source-build validation leg doesn't use any of the source-built arcade packages.

@akoeplinger discovered this previously here: dotnet/arcade#8355

This can be observed in the binlog by examining the task assemblies used. Many of the packages/SDKs (including arcade SDK itself) are using non-source built packages.

Source-build is tracking fixing the route problem in dotnet/arcade#8642

This issue will track removing workarounds from dotnet/runtime.

I couldn't figure out the best area label to add to this issue. If you have write-permissions please help me learn by adding exactly one area label.

Closing this as we chose not to workaorund it in dotnet/runtime and instead are working around in arcade. dotnet/arcade#8597
