SUMMARY
 I'd like the "On AC Power" state to be redefined to "Battery not discharging".

ELABORATION
My work laptop has a 150W charger, but it's normally connected to a USB-C hub
which delivers less power that that. I believe it's 65W. Normally that's fine
but at times a non-KDE browser that shall not be named decides to keep my cores
busy. And when that happens, the laptop needs more power than the hub can
deliver, drawing the extra power it needs from the battery.

When that happens, because it's technically connected to power, the "On AC
Power" settings keep being applied, causing it to ultimately just die without
me getting any warning that I'm in trouble beforehand. The battery widget will
not raise any alarm and neither is the setting for "At critical level" (shut
down in my case) ever applied. This stupid laptop then needs to charge using
its own charger for about 12 minutes before it will even turn on again.

I'd therefore like to see the following changes:
1. Redefine the "On AC Power" state to "Battery not discharging" and "On Batter
Power" to "Battery discharging" (fwiw, I think the naming doesn't need to
change, just the definition)
2. This should be used by both the power state guard thingamajig and the
battery widget, so that:
    1. The widget shows that the battery is discharging, even when on AC power
    2. The "On Battery Power" state is used when discharging, even when on AC
power
    3. The "Advanced Power Settings" are honored when discharging, even when on
AC power

This way, any such future events can be prevented.

STEPS TO REPRODUCE
1. have a power-hungry laptop
2. connect to USB-c hub that can deliver less power than the laptop needs under
full load
3. get the CPU busy

OBSERVED RESULT
1. The battery widget doesn't indicate that the battery is discharging
2. The battery widget doesn't raise the alarm when battery power is low
3. The laptop just dies while the power scheme clearly states that it should
shut down when reaching 10% battery power

EXPECTED RESULT
1. The battery widget should display, indicating that the battery is
discharging
2. The battery widget should raise the alarm when the battery level is low
3. The laptop should honor the "At critical level" setting under "Advanced
Power Settings"
