Simplify lazy_static dependency

Summary:
1. `lazy_static` has no default features so `default-features = false` has no effect.

2. The `spin_no_std` feature is not something that you would want in builds where a standard library synchronization primitive like `std::sync::Once` is available, only in the no-std universe, where it is already controlled by this:

The `spin_no_std` feature will sadly remain enabled for now due to a misguided use of it in the `num-bigint-dig` crate, which is a dependency of our default universe.
