The max30101 allows to configure time slots in samples acquisition.
It is now supported by adding matrix mapping for the slot/fifo
indexing. When a channel is present multiple times, the resulting
sample from the `sensor_channel_get` is averaging each entry.
Added Die temperature sample acquisition with
`CONFIG_MAX30101_DIS_TEMPERATURE` Kconfig.

The size of icm45686_encoded_data fifo_payload is guaranteed
to span the full number of frames read as it was allocated during
icm45686_event_handler() buf_len_required size.

out of bounds memory access at index 1 by explicitly declaring
fifo_payload to be a VLA at the end of icm45686_encoded_data.

When operating in streaming mode, a FIFO empty event, which
is caused by host reading the last byte of the last FIFO frame,
can cause FIFO data corruption.
During subsequent reads to the FIFO, the first frame that arrives
after the empty condition will be corrupted. Once the issue occurs,
the internal state cannot recover and the FIFO must be flushed in
bypass mode to clear the corrupted state.
The current workaround from TDK is to read M-1 frames when M frames
are reported by fifo_count. Since M is fixed by the fifo_watermark
DT parameter, and in cases where fifo_watermark == 1, the watermark
trigger threshold is set to M + 1 frames and M frames are read out
during a watermark threshold event.

Update the temperature data processing to
handle different data sizes based on FIFO configuration.
The temperature sensor data size and conversion
formula vary depending on the FIFO mode:
1. FIFO disabled: Uses 20-bit data format
2. FIFO enabled (standard resolution): 16-bit data
3. FIFO enabled (high resolution): 20-bit data
The implementation now:
- Uses the 'fifo_highres_enabled' flag
to determine the correct data size
- Applies the appropriate conversion formula
based on the resolution mode
- Handles all three possible FIFO configurations
- Ensures accurate temperature readings in all modes

Move the watermark threshold trigger mode to a configurable dt boolean.
When using the default configuration of watermark threshold
interrupt greater than or equals, extra interrupts are serviced
to icm45686_event_handler().
When `fifo-watermark-equals;` is added to the sensor DT overlay,
the new behavior is only one interrupt is generated per watermark
threshold crossing. Until the host drains the fifo, no extra interrupts
will be generated.

Extend the LIS2DU12 accelerometer driver with SENSOR_TRIG_DELTA
support. The detection is based on the slope between successive
channel readings. Support for setting SENSOR_ATTR_SLOPE_TH and
SENSOR_ATTR_SLOPE_DUR is added as well. In line with other sensors,
SENSOR_ATTR_SLOPE_TH is configured in SI units (m/s^2) and
SENSOR_ATTR_SLOPE_DUR in samples relative to the ODR. The new trigger
can be mapped either to the same GPIO as the data-ready interrupt or
to a dedicated one.
