Switch to back to ValidationResult for results when validating a token.

[brentschmaltz]

This PR returns to returning ValidationResult defined in IdentityModel.

This resolves issues:

1. When 8.x assemblies have different versions: [Bug] Version 8.13.1 breaks CoreWCF (MissingMethodException) #3291
2. Remove dependency on Microsoft.Identity.Abstractions: Why does Microsoft.IdentityModel.Tokens 8.13.1 now depend on Microsoft.Identity.Abstractions? #3290
