sensors: Implement Single Tap Sensor

- This implements a modernized tap to wake sensor for devices that support it. - It is guarded by a SOONG variable hence to use it, a maintainer would have to configure it in the BoardConfig. - An example is as below: SOONG_CONFIG_NAMESPACES += SENSORS_XIAOMI SOONG_CONFIG_SENSORS_XIAOMI += USES_SINGLE_TAP_SENSOR SOONG_CONFIG_SENSORS_XIAOMI_USES_SINGLE_TAP_SENSOR := true Change-Id: I30d190d0f07ca2517826cc2263153ad39bacc204 Signed-off-by: Cyber Knight <[email protected]>
