pcbnew: Adding PCB_BOARD_OUTLINE item for contrast between board and external space
This pull request adds PCB_BOARD_OUTLINE item in pcbnew for better contrast between board and external space related to #8112:
While introducing the default board backgound color proposed in !1752 (comment 1689109163) , User can change it in Preference->PCB Editor->Colors->Board outline:
The shape is updated while the BoardPolygonOutline changes , showing the board bounding box instead if no valid outline found
