* implement async for lcd_cam i8080
* lcd_cam: implement InterruptConfigurable for blocking and improve async
* lcd_cam: use new async interrupt semantics from #1835
* lcd_cam: move interrupt handler binding into `new_async()`
* lcd_cam: Instance::is_listening_lcd_done not used
* i8080: no need for seperate `new_async()`
* i8080: don't use DmaTxFuture, just test for dma error after complete
* add HIL tests for LCD_CAM i8080 in blocking and async.
* lcd_cam_i8080: test channels configured for async as well since teh compiler can't prevent it for now
* fmt :-/
* lcd_cam fix comment
