Change FunctionParam to represent variadic params
Variadic were represented at the function level while retaining most
informations of a given parameter.
gcc/rust/ChangeLog:
* ast/rust-item.h (class FunctionParam): Add some informations to
function parameters in order to be able to store variadic argument as
a function parameter.
