Implement more methods for `vec_deque::IntoIter`
This implements a couple `Iterator` methods on `vec_deque::IntoIter` (`(try_)fold`, `(try_)rfold` `advance_(back_)by`, `next_chunk`, `count` and `last`) to allow these to be more efficient than their default implementations, also allowing many other `Iterator` methods that use these under the hood to take advantage of these manual implementations. `vec::IntoIter` has similar implementations for many of these methods. This PR does not yet implement `TrustedRandomAccess` and friends, as I'm not very familiar with the required safety guarantees.

Deny non-lifetime bound vars in `for<..> ||` closure binders
Moves the check for illegal bound var types from astconv to resolve_bound_vars. If a binder is defined to have a type or const late-bound var that's not allowed, we'll resolve any usages to ty error or const error values, so we shouldn't ever see late-bound types or consts in places they aren't expected.

this code was already unreachable. Also we removed the no_hash + feeding restriction in https://github.com/rust-lang/rust/pull/105220.
Don't recover lifetimes/labels containing emojis as character literals
Fixes#108019.
Note that at the time of this commit, `unic-emoji-char` seems to have data tables only up to Unicode 5.0, but Unicode is already newer than this.
A newer emoji such as `🥺` will not be recognized as an emoji but older emojis such as `🐱` will.
This PR leaves a couple of FIXMEs where `unic_emoji_char::is_emoji` is used.
