These are moved: * Display -> busdisplay.BusDisplay * FourWire -> fourwire.FourWire * EPaperDisplay -> epaperdisplay.EPaperDisplay * I2CDisplay -> i2cdisplaybus.I2CDisplayBus `paralleldisplay` is now `paralleldisplaybus` (and registered as `paralleldisplay` too). Bus related helpers are split out of display_core into bus_core. It is in still displayio since it is a dependency of both busdisplay and epaperdisplay. Fixes #7667
