Remove default binds for DirectInput

As requested.

DirectInput-only controllers are already getting rarer and rarer. Plus, this branch makes all controllers faster & simpler to rebind. I'd even argue these get in the way, because you can't just immediately bind a DInput controller from boot-up, you have to unbind everything first.

I'm not against a new code path for DInput defaults that tries to guess what kind of controller you have, but I don't care about it myself.
