Enforce Copy bounds for repeat elements while considering lifetimes

fixes https://github.com/rust-lang/rust/issues/95477

this is a breaking change in order to fix a soundness bug.

Before this PR we only checked whether the repeat element type had an `impl Copy`, but not whether that impl also had the appropriate lifetimes. E.g. if the impl was for `YourType<'static>` and not a general `'a`, then copying any type other than a `'static` one should have been rejected, but wasn't.
