Choose measurement strategy on time nodes

[Remi123]

Godot version: 4.2

Describe the bug
Both delayer and cooldown update their internal timer using get_physics_process_delta_time() on each tick. However, if you update your tree every 20 frame just like I do, this mean that it take 20 time the desired amount.

There is a few ways to make it tick-independent. I would store the time at before_run, then each tick compare if the difference betwen now and then is higher than the desired amount. But you could also create_timer.

To Reproduce
Add a Cooldown or delay node, set a wait_time to 1.
set the behavior tree tick rate to 20.
Wait 20 second to see the desired behavior.

Expected behavior
waiting 1 second

The only feasible way I see here is to add a new enum to time dependent nodes that define how the is measured, e.g. "tick based" or "clock based"

Each has their use-cases. I will implement this for V3
