cli: Properly support token-2022 mints

#### Problem

Although the stake pool program allows for mints on token-2022, the CLI
still does not.

#### Summary of changes

A few changes:

* use spl-token-2022 for instruction creators
* allow for the token program id to be spl_token::id() or
  spl_token_2022::id()
* derive ATAs with the token program id
* use the token program id stored on the stake pool
* during pool creation, return a helpful error if the mint is configured
  incorrectly
* add a test script using token-2022
