Daniel Rainer e16ea8df11 sync: once_cell::sync::OnceCell -> std::sync::OnceLock ...

Rust 1.70 stabilized `std::sync::OnceLock`, which replaces
`once_cell::sync::OnceCell`.

With this, we only have a single remaining direct dependency on
`once_cell`: `VAR_DISPATCH_TABLE` in `src/env_dispatch.rs`, where we use
`Lazy::get`. This can be replaced with `LazyLock::get` once our MSRV
reaches 1.94, where the function is stabilized.

At the moment, `serial_test` depends on `once_cell`, so even if we
eliminate it as a direct dependency, it will remain a transitive
dependency.

Closes #12289
