ICE(non_lifetime_binders): const bound params not handled correctly

[camelid]

After #125915 is merged, this code from the testsuite for the incomplete non_lifetime_binders feature will ICE instead of erroring. This was decided to be acceptable for now.

#![feature(non_lifetime_binders)]
//~^ WARN the feature `non_lifetime_binders` is incomplete

fn b()
where
    for<const C: usize> [(); C]: Copy,
    //~^ ERROR cannot capture late-bound const parameter in constant
{
}

fn main() {}

warning: the feature `non_lifetime_binders` is incomplete and may not be safe to use and/or cause compiler crashes

Will make sure to actually check there's not something trivial we can do to make this work before merging the PR but for now this is nice to not block a passing CI ✨

[compiler-errors]

Fixing this the right way would require adding where clauses to binders (so we can put constparamty preds on the binders). Maybe I should just bite the bullet and do that 💀

[compiler-errors]

Would be fine if we just outright denied consts from non-lifetime-binders for the moment tho. There's never a case where they work currently, and adding support for them (compared to types) was just a fun addition when I impl'd it.
