New version of some OOB packages

New versions of some out-of-band (OOB) packages were generated. The following changes were made that can be considered breaking:

• The supported target framework monikers (TFMs) were updated.
• The package version minor number was updated.
• In some cases, some TFMs are no longer supported.

Additionally, the source code of these packages was migrated from their old location, which was a branch of .NET that is no longer in support, to the https://github.com/dotnet/maintenance-packages repo.
