[refactor] deprecate lazy_static

[lightsing]

Description

The crate lazy_static is deprecated in May 4 by rust-lang-nursery/lazy-static.rs#214
This PR migrate all lazy_static usage to once_cell.

Future works

It's worth noting that many of our APIs, such as Word::zero and address!(), could benefit from being available as const.
As we can get rid of Lazy::new(|| ...) and replace them with const SOMETHING: Word = Word::zero().
Moving forward, we should make these APIs available as const functions.

For reference, primitive-types = "0.12.1" has U256::zero as const fn

const parser marco: #918

@lightsing i think this is outdated since when you upgraded rust, this was already fixed?
