output: Add color-representation to output state

Browse source 
Add color_representation to wlr_output_state, holding color
representation metadata about the primary buffer.  This can be set
using wlr_output_state_set_primary_color_representation() and a
new enum value WLR_OUTPUT_STATE_COLOR_REPRESENTATION in
wlr_output_state.committed indicates when this data is present.

Also add color-representation to wlr_output, and discard
color-representation in wlr_output_state if it matches what's already
been committed to the output.
