DesignTimeBuild is included in ResolvePackageAssets HashSettings

[nguerrera]

This will cause the cache to be rebuilt always when building after a design time build, or design time building after a build.

The test was updated to allow DesignTimeBuild to not be in the cache:

sdk/src/Tasks/Microsoft.NET.Build.Tasks.UnitTests/GivenAResolvePackageAssetsTask.cs

Line 21 in de72490

p.Name != nameof(ResolvePackageAssets.DesignTimeBuild))

But it is actually written:

sdk/src/Tasks/Microsoft.NET.Build.Tasks/ResolvePackageAssets.cs

Line 376 in de72490

writer.Write(DesignTimeBuild);

Probably need a test that checks the opposite of the settings hash test for DesignTimeBuild: that you can change it without influencing the hash.
