Add Sync bound to allocator parameter in vec::IntoIter The `A: Sync` bound was forgotten in https://github.com/rust-lang/rust/commit/8725e4c33749b23f260b2fc46e090c3792b6f97e#diff-b78c3ab6d37f4ede32195707528f8a76c49d4557cc9d3a7a09417b5157729b9fR3132 Similar `unsafe impl Sync` in that commit _do_ include the `A: Sync` bound (and around the alloc lib), so I think this was just an honest mistake. Here's an example of the unsoundness: https://play.rust-lang.org/?version=nightly&mode=debug&edition=2021&gist=16cbfeff7c934ae72ab632c1476fdd8b `@steffahn` found this, I'm just putting up the fix cause nobody else did :^) Fixes #92633
