Since rust 1.61, the underlying const functions are available in stable rust, and lock_api >= 0.4.7 automatically uses them. (Feature const_fn_trait_bound, https://github.com/rust-lang/rust/pull/93827)
To avoid a breaking change, the features are still listed in Cargo.toml, but have no effect and are marked as deprecated. This bumps the minimum supported rust version to 1.61.
