[rust] Upgrade to rust 1.55.0

1. Rust-1.53.0 has [`IntoIterator` for arrays](https://blog.rust-lang.org/2021/06/17/Rust-1.53.0.html#intoiterator-for-arrays)
   which is needed for the `collection!` macro.
2. Rust-1.54.0 re-enabled incremental compilation, which was disabled in
   1.52.1.
3. Rust-1.55.0 updates `std::io::ErrorKind` variants and supports open ranges
   in patterns.
