Upgrade all dependencies

[ia0]

We're holding 2 things behind:

• The toolchain because of panic=immediate-abort with build-std doesn't work: the crate core was compiled with a panic strategy which is incompatible rust-lang/rust#146974. We'll wait until Add panic=immediate-abort support to Cargo rust-lang/cargo#16041 is fixed to update.
• The WebAssembly spec because non-trivial changes might be needed to update the interpreter (or at least the test-suite).

Code Review

This pull request upgrades a large number of dependencies across the project. The changes are mostly in Cargo.toml and Cargo.lock files, which is expected for this kind of update. I've reviewed the code changes made to adapt to new APIs, and they seem correct. This includes the switch from doc_auto_cfg to doc_cfg due to Rust toolchain updates, and the adaptation to the new otcrypto_sha2_* API in crates/runner-opentitan/src/crypto/hash.rs following the opentitan submodule update. The update of mdbook and assemblyscript versions are also correctly handled. Overall, this is a solid dependency upgrade.
