Build pipeline is reporting warnings for files that are configured as exclusions

[Colin]

Hey Andrew.

Exclusions are only taken into account during the Run Code Analysis step, not during the build when the Roslyn analyzers are run. Hopefully we’ll improve on that this year.

@Andrei_Epure

We have this on our internal roadmap to improve (i.e. treat exclusions in the Roslyn analyzer, not when importing the Roslyn results after the build).
