Make the `atomic` feature of `solana-address` dependency optional. Fixes: anza-xyz#301

This is technically a breaking change, but it won't be destructive! Since |

Actually running into this issue now as well. From what I can tell the solana-atomic crate should just be able to import atomic from core instead of std. Doesn't solve the issue for #[cfg(not(target_pointer_width = "64"))] with parking lot though |

#### Problem The pubkey crate doesn't compile for no-std environments because the atomic feature is always enabled on address. This is an alternative to anza-xyz#302. #### Summary of changes Add the "atomic" feature to the "std" feature in pubkey, and enable "std" as appropriate for certain tests. We could do the same with "decode", but since it isn't required, I'm inclined to make a minimal change. People can switch to address for more control.

Let's ship #388 instead |
