drivers/sensor: lis2dux12: re-working to be DUX generic

Prepare the driver to be able to handle other DUX software compatible
devices. Currently the driver handles the st_lis2dux12 compatible only.

Do following major changes:

1. Introduce the lis2dux12_chip_api structure filled with device specific
   APIs. At the moment define following callback:

    - api_lis2dux12_set_odr_raw()
    - api_lis2dux12_set_range()
    - api_lis2dux12_sample_fetch_accel()
    - api_lis2dux12_sample_fetch_temp()
    - api_lis2dux12_handle_interrupt()
    - api_lis2dux12_init_interrupt()

2. Prepare specific APIs for st_lis2dux12 device.

3. Make DT instantiation on inst + name basis, and not only by inst. This
   commit only use "name = DT_DRV_COMPAT = st_lis2dux12".
