[RTL] actctx.c: Use an alternative implicit activation context when an application is built for latest windows versions.

Browse source 
Instead of loading systemcompatible.manifest as the implicit activation context, load forwardcompatible.manifest
Add a new assembly containing all apisets called ReactOS.Apisets and make it a dependency to forwardcompatible.manifest
