Bring back Microsoft.Bcl.AsyncInterfaces (#40189)

Bring back Microsoft.Bcl.AsyncInterfaces (#40189)

* Bring back Microsoft.Bcl.AsyncInterfaces

This is needed in order to build a version of this assembly that uses
the latest version of its dependency System.Threading.Tasks.Extensions

Without this, we'd reference in inconsistent set of versions for S.T.T.E
in libraries that use both AsyncInterfaces and S.T.T.E.
