Arcade-Validation should also test building using VS

Additionally from building using the SDK bootstrapped from the tools.dotnet we should also test building using the msbuild from VS to avoid regressions in that codepath.

Description of how to enable this in global.json

Have to consider that the global.json should only have the vs section for this one build job.

CC/ @mjanecke Issue discussed during retrospective today. Should this go into the epic you've been working on?

Should be able to split the build into two jobs and one will build the same repo (arcade-validation) but with VS.

Outside the scope of the #3671 epic. Moving to #8587 epic (MORE Validation)

[missymessa]

Keeping this one. It's building Arcade using VS versus MSBuild.
