output: introduce wlr_output_set_name

Browse source 
wlroots picks names for all outputs, but it might be desirable for
compositor to override it.

For instance, Sway will use a headless output as a fallback in
case no outputs are connected. Sway wants to clearly label the
fallback output as such and label "real" headless outputs starting
from HEADLESS-1.
