Add analyzers that suggest replacing obsoleted GetData APIs with the new typed versions

[Tanya-Solyanik]

1. suggest using POCO types for data exchange to simplify resolver implementation, and potentially suggest opting out from the OOB formatters assembly if not needed for other reasons.
2. replace GetData for POCO types or primitives and known types wth the TryGetData analog with no resolver
3. point to sample resolvers in github.com/dotnet/samples/windowsforms when getting more complex types.
