2024-10-25gccrs: Fix bad recursive operator overload callPhilip Herron6-6/+134
When we are typechecking the impl block for DerefMut for &mut T the implementation follows the usual operator overload check but this ended up just resolving directly to the Trait definition which ends up being recursive which we usually handle. The issue we had is that a dereference call can be for either the DEREF or DEREF_MUT lang item here it was looking for a recurisve call to the DEREF lang item but we were in the DEREF_MUT lang item so this case was not accounted for.

2024-09-27rust: Add support for Clone and Copy derive on generic typesPhilip Herron16-22/+783
When we generate derivations for Copy and Clone we need to make sure the associated impl block sets up the generic parameters and arguments correctly.
