Qingsong Chen 3fa7187ece rust: macros: vtable: fix `HAS_*` redefinition (`gen_const_name`)
If we define the same function name twice in a trait (using `#[cfg]`),
the `vtable` macro will redefine its `gen_const_name`, e.g. this will
define `HAS_BAR` twice:

    #[vtable]
    pub trait Foo {
        #[cfg(CONFIG_X)]
        fn bar();

        #[cfg(not(CONFIG_X))]
        fn bar(x: usize);
    }

Fixes: b44becc5ee ("rust: macros: add `#[vtable]` proc macro")
