Output parameters transformation improvements

For supporting output parameters we returned a table but this was generating a lot of code to build that table before leaving the procedure. Also, the returned type was complex to build and confusing.

Now, we are returning an object in a single line and the type was changed to VARIANT. From the procedure calls, the migrator generates the needed code to retrieve the variables from the generated object. The new implementation is cleaner and easier to understand.
