Improve sql logging coloration in `ActiveRecord::LogSubscriber`.

- Improves coloring for statements like:

    # Become WHITE
    SELECT * FROM (
        SELECT * FROM mytable FOR UPDATE
    ) ss WHERE col1 = 5;
    LOCK TABLE table_name IN ACCESS EXCLUSIVE MODE;

    # Becomes RED
    ROLLBACK

- Reinstates the coloration of the `payload[:name]`.
  Instead of simple alternating colors, adds meaning:
  - `MAGENTA` for `"SQL"` or `blank?` payload names
  - `CYAN` for Model Load/Exists

- Introduces specs for sql coloration.
- Introduces specs for payload name coloration.
