Add a non generic overload to ForDestinationType

[Dewera]

There's been a few scenarios where I've only had access to a Type at runtime and have needed to setup destination mapping rules for these, which isn't possible when there is only a function that takes generic parameters. This PR adds an overload that does the same thing but takes a Type function parameter instead of a generic one.
