Temporarily add back old TryParse signatures (dotnet/coreclr#14893)

My previous change updated the primitive TryParse signatures based on
the new design, but until corefx consumes that change, live corefx bits
won't work with the latest coreclr bits.  Until it can be consumed, I'm
putting back the old signatures as well.
