Update rustls to version 0.23
Updates the code to compile with newer versions of `rustls` and `rustls_pemfile`. Replaces `lazy_static` with `std::sync::LazyLock`, because `lazy_static` could not handle `async move` construct for unknown reason, and it's recommended to replace it anyways. Fixes some warnings generated by `cargo clippy`, mostly lifetime elisions. I didn't fix the warnings regarding the large size difference between variants of enums, because I wasn't sure about the correct fix. The `Poll:Ok` would probably still return the large data instead of the Box anyways.
