output/config: Remove reset_outputs and co.

apply_output_config_to_outputs uses the specified output config to check
which outputs to apply to, and to use as backup when no config is found.
If any config matches the output, the specified config will be
disregarded.

The only remaining user of apply_output_config_to_outputs is
reset_outputs, which called apply_output_config_to_outputs with either
the first stored wildcard config, or a new empty wildcard config.

Providing a stored or empty wildcard config is practically the same as
calling `apply_all_output_configs`. Replace uses of `reset_outputs` with
`apply_all_output_configs` and remove the now unused functions.
