[touch] Use sw double taps based on input policy state. Fixes JB#33873

MCE uses simulated double taps detected from normal touch event flow only
when touch devices have been grabbed by mce. Especially for protocol B
multitouch input devices, the grabbing might not be possible/allowed
and thus the simulated double taps are never accepted.

Use sw double taps when input policy indicates grabbing should take
place instead of when the grabbing has actually happened.
