Improve touch detection logic used in blanking policy handling
Improve touch detection logic used in blanking policy handling

Notification and linger blanking policy states should be affected by
touch screen activity. Unlike double tap detection, this has not been
updated to work with various variants of multitouch protocol and works
reliably only on Jolla phone.

Update the touch detection code to use similar logic as the double
tap detection is using.

[mce] Improve touch detection logic used in blanking policy handling. Fixes JB#30661
