Centralize fix for nullability annotations in netstandard builds (dotnet/corefx#42391)

* centralize fix for nullability in netstandard2.0

* remove project property from conditional

* Revert "remove project property from conditional"

This reverts commit dotnet/corefx@ffc54a15a4589381b3bd78aa5b3ef020c8a1c75e.

* move to Directory.Build.targets

* Add netcoreapp2.x check

* update logic for projects that use nullable annotations without it being enabled

* add nullable property to System.Data.SqlClient

* address newly added annotated project

* add nullable annotations to System.Security.Cryptography.Pkcs

Commit migrated from https://github.com/dotnet/corefx/commit/e52be6965496af9de49de585e6c62bdb0915c775
