gccrs: Reject auto traits with generic parameters
Generic parameters are not allowed on auto traits, the compiler should
emit an error.
gcc/rust/ChangeLog:
* checks/errors/rust-ast-validation.cc (ASTValidation::visit): Add
check for generics on auto traits.
* checks/errors/rust-ast-validation.h: Add visit function prototype.
