The default implementations of several `Iterator` methods use `fold` or `try_fold`, which works, but is overkill for slices and bloats the amount of LLVM IR generated and consequently hurts compile times. This commit adds the simple, obvious implementations for `for_each`, `all`, `any`, `find`, `find_map`, and simplifies the existing implementations for `position` and `rposition`. These changes reduce compile times significantly on some benchmarks.
Currently it uses `for x in self`, which seems dubious within an iterator method. Furthermore, `self.next()` is used in all the other iterator methods.
PrefixComponent with Prefix::VerbatimDisk does not contain the trailing slash. The documentation here is also inconsistent with the documentation on other variants that reflect the `PrefixComponent::as_os_str()` return value.

Update transitive dependency to work towards removing syn <1.0 dep This bumps a couple of transitive dependencies in hopes of eventually not transitively depending on syn <1.0 and friends. The only upstream changes that this is blocked on seems to be mattico/elasticlunr-rs#27 and rust-lang/mdBook#1210. While working on rust-lang#71875 I noticed we still use syn 0.15 here and there so this is a drive-by PR which aims to help with things a bit.

Remove `lang_items\(\).*\.unwrap\(\)` Follows up rust-lang#72170 to remove the remaining uses of `lang_items\(\).*\.unwrap\(\)` (avoids a bunch of potential ICEs when working in `#![no_core]`). Resolves rust-lang#72195
Updated documentation of Prefix::VerbatimDisk PrefixComponent with Prefix::VerbatimDisk does not contain the trailing slash. The documentation here is also inconsistent with the documentation on other variants that reflect the `PrefixComponent::as_os_str()` return value.
Implement Default for proc_macro::TokenStream Hopefully this is uncontroversial. The only reason we've made it this far without is that proc-macro2 snuck this in for their TokenStream.
