toolchain: update to Rust 1.68.0

Routine update to the latest version of Rust.
Release post: https://blog.rust-lang.org/2023/03/09/Rust-1.68.0.html

I don't see anything exciting for nearcore in the release.
Maybe `pin!` for custom futures could be useful.

The commit also includes clippy renaming `derive_hash_xor_eq`
to `derived_hash_with_manual_eq`.

There is also a new [future incompatibility warning](rust-lang/rust#103418)
which we hit in `fs_extra v1.2.0` and `wasmparser v0.78.2`.
I don't think we can get rid of the second anytime soon, assuming we
hang on to replayability.
