Add default exceptions affected by suppress (#25099)

* Add default exceptions affected by suppress

    suppress { do_something_that_might_fail }

    # instead of

    begin
      do_something_that_might_fail
    rescue
    end

    # or

    do_something_that_might_fail rescue nil

* Do not add default exceptions list constant
