Avoid box allocation in Encoding.EncodingName (dotnet/coreclr#6142)

`Encoding.EncodingName` concatenates a `string` with an `int` via
`string.Concat(object, object)`, which results in the `int` being
boxed.

This change avoids the box by calling `int.ToString()`,
allowing `string.Concat(string, string)` to be used.
