driver/sensor: lis2dw12: single/double tap trigger implementation

Browse source 
Implementation for two new interrupt triggers: single tap and
double tap. Add new Kconfig options to configure those triggers:
trigger mode (single/single and double), latency/quiet/shock time,
threshold levels, active axes.
