4bc429019dc4bff6af0f9824ad6ab6745f09f8ba Add a secp256k1_i128_to_u64 function. (Russell O'Connor)

Pull request description:

  I wanted to experiment with what would be required to split up `secp256k1_i128_to_i64` between those cases when a signed 64 bit value is being demoted, versus an unsigned 64 bit value is being extracted from the lower bits, and this is the result.

  I'm not sure this is a useful PR, so feel free to close it.  However, since it is already written, I figured it is worth at least discussing.
