This simplifies the way that we publish files to our network drop share.
Changes:
* Instead of explicitly listing every file that needs to publish, use directories to classify packages and artifacts into different categories.
* Add documentation for the expected layout of artifacts/
* Remove the need for static analysis to determine which packages go to which project
* Add the MSBuild property "IsProductPackage" to .csproj files which ship as a package to NuGet.org.
- #4866 3 of 3
- other than ignored parameters and properties, no vestige remains of alternate behaviours
- also remove `AllowAreas` use outside src/Mvc
- left the `IEnumerable<ICompatibilitySwitch>` implementations to avoid `breakingchanges.netcore.json` churn
- made the implementations more consistent
- left one `ConfigureCompatibilityOptions<MvcOptions>` subclass: `MvcOptionsConfigureCompatibilityOptions`
- note `AllowShortCircuitingValidationWhenNoValidatorsArePresent` default now applies to `TryValidateModel(...)` etc.
nits:
- updated `CompatibilityVersion` doc comments
- "currently unused" -> "currently ignored" in doc comments from part 2
- took a few VS suggestions
- VS seems to have cleaned up some trailing whitespace in files I had opened but didn't manually change
- Stop producing the 'Universe' lineup package
- Removes all PackageLineup code
- Use full msbuild on Windows
- Fix invalid reference to internal.aspnetcore.sdk in 2.1.x
- Fix shared folder references for PackageArchive task.
