Cranelift: Remove the ABICaller trait (#4711)

Browse Source 
* Cranelift: Remove the `ABICaller` trait

It has only one implementation: the `ABICallerImpl` struct. We can just use that
directly rather than having extra, unnecessary layers of generics and abstractions.

* Cranelift: Rename `ABICallerImpl` to `Caller`
