godot: [3.5.rc6] Broken touch input on iOS

Godot version

3.5 RC6

System information

iOS

Issue description

Touch input on iOS became unresponsive in RC6 vs. RC5. I know about the change in the default for accumulated input.

But:

1. It works on Android
2. It doesn’t work any longer on iOS (both with iOS touch delay = 0.01 in our project and the default of 0.15)
3. It still doesn’t work on iOS by calling Input.set_use_accumualted_input(true)

I’ll have to extract the touch controller code (again) to provide an MRP. Let me know if whoever tries RC6 with iOS cannot reproduce the problem. Thanks.

Steps to reproduce

Try an existing project known to be working with touch input on iOS + Godot 3.5 RC6 😃
