cli: remove deprecated Errors type
The Errors type was deprecated in d3bafa5f3e,
which has been included in the 27.4.0 release.

This patch removes the type, as there are no external consumers.

cli: deprecate Errors type
The Errors type is no longer used by the CLI itself, and this custom
"multi-error" implementation had both limitations (empty list not being
`nil`), as well as formatting not being great. All of this making it not
something to recommend, and better handled with Go's stdlib.

As far as I could find, there's no external consumers of this, but let's
deprecate first, and remove in the next release.

cli: make cli.StatusError slightly prettier
This error didn't do a great job at formatting. If a StatusError was
produced without a Status message, it would print a very non-informative
error, with information missing.

Let's update the output:

- If a status-message is provided; print just that (after all the
  status code is something that can be found from the shell, e.g.
  through `echo $?` in Bash).
- If no status-message is provided: print a message more similar to
  Go's `exec.ExecError`, which uses `os.rocessState.String()` (see [1]).

Before this patch, an error without custom status would print:

    Status: , Code: 2

After this patch:

    exit status 2

In situations where a custom error-message is provided, the error-message
is print as-is, whereas before this patch, the message got combined with
the `Status:` and `Code:`, which resulted in some odd output.

Before this patch:

    docker volume --no-such-flag
    Status: unknown flag: --no-such-flag
    See 'docker volume --help'.

    Usage:  docker volume COMMAND

    Manage volumes

    Commands:
      create      Create a volume
      inspect     Display detailed information on one or more volumes
      ls          List volumes
      prune       Remove unused local volumes
      rm          Remove one or more volumes
      update      Update a volume (cluster volumes only)

    Run 'docker volume COMMAND --help' for more information on a command.
    , Code: 125

With this patch, the error is shown as-is;

    docker volume --no-such-flag
    unknown flag: --no-such-flag
    See 'docker volume --help'.

    Usage:  docker volume COMMAND

    Manage volumes

    Commands:
      create      Create a volume
      inspect     Display detailed information on one or more volumes
      ls          List volumes
      prune       Remove unused local volumes
      rm          Remove one or more volumes
      update      Update a volume (cluster volumes only)

    Run 'docker volume COMMAND --help' for more information on a command.

While the exit-code is no longer printed, it's still properly handled;

    echo $?
    125
