driver: lis2dw12: Add driver support

Added ACC LIS2DW12 driver support.
Features included in this driver are:
   - Basic Sensor Read acceleration data
   - ODR and FS runtime configuration
   - FIFO support with watermark interrupt events
   - Shared commons function with ST MEMs devices
   - Switch Low Power to High perf. mode in case
     of ODR > 200 Hz
   - Configure D-TAP event detection in Hardware

BUG=b:73546254
BRANCH=master
TEST=Tested on discovery_stmems target BOARD with
LIS2DW12 connected to EC i2c master bus and motion
sense task running.

To build firmware for discovery_stmems target with
LIS2DW12 sensor connected, simply uncomment
CONFIG_ACCEL_LIS2DW12 define in board.h target file
and make with target BOARD=discovery_stmems.

Commands used to test LIS2DW12 device are:
   - accelinit 0 (to configure accel. device)

All basic features tested, including changing
in ODR:
   - accelrate 0 10000 (set ODR to 10 Hz)
   - accelrate 0 12500 (set ODR to 12.5 Hz)
   - accelrate 0 25000 (set ODR to 25 Hz)
   - accelrate 0 50000 (set ODR to 50 Hz)
   - accelrate 0 100000 (set ODR to 100 Hz)
   - accelrate 0 200000 (set ODR to 200 Hz)
   - accelrate 0 400000 (set ODR to 400 Hz)
   - accelrate 0 800000 (set ODR to 800 Hz)
   - accelrate 0 1600000 (set ODR to 1.6 kHz)

Full Scale Range:
   - accelrange 0 2 (set Full Scale Range to 2g)
   - accelrange 0 4 (set Full Scale Range to 4g)
   - accelrange 0 8 (set Full Scale Range to 8g)
   - accelrange 0 16 (set Full Scale Range to 16g)

FIFO features and interrupt management:
   - accelinfo on 1000 (motion info task with
                        refresh rate 1 s)

and polling data read:
   - accelread 0 (to read data from accelerometer)
