Regression of #12418 ([2.0.x] Filament Runout Sensor sporadic false positive when using FILAMENT_RUNOUT_DISTANCE_MM > 0)

[ghost]

Please refer to issue #12418 ([2.0.x] Filament Runout Sensor sporadic false positive when using FILAMENT_RUNOUT_DISTANCE_MM > 0), which I have reopened. After some testing I have identified the point in time during the last month when this regression occurred. The bug is back to due to a regression introduced by commit #12547 (Add poll_runout_states, which returns 1 for runouts)

I am getting the invalid runout event immediately after the print process begins extruding, and the event occurs repeatedly immediately from then on.

Prior to #12547, no problem. After #12547: Problem occurs. I have tested these two time-points on my printer.

Ok, I found the problem: The value of FIL_RUNOUT_INVERTING is now inverted due to this commit. I used to use false, I now had to set it to true. I think this corresponds better to the actual situation in my printer: The switch pulls down to GND.
