cli_util: always run custom global-args-processing function

Browse source 
The way I added support for processing custom global arguments - by
using the existing `dispatch_fn` - meant that it wouldn't be run if
`CliRunner::add_global_args()` was called before
`CliRunner::add_subcommand()` and the custom subcommand wasn't
run. That's clearly not what I intended. This commit fixes that by
adding a separate list of functions for processing global args.
