Add toggle logic inside DPMS handler 

Logic that obtains current DPMS state is put inside the handler.

sway_output from which the current DPMS state will be obtained is selected by the following logic:
* For '-' and '--' the focused output is used;
* For '*' error "Cannot apply toggle to all outputs" is reported;
* For everything else all_output_by_name_or_id() is used.

Fixes #5929.
