This commit introduces a new Sensor Clock API, enabling the retrieval
of cycle counts and conversion to nanoseconds based on the system or
external clock. The API includes:
- `sensor_clock_get_cycles()` to get the current cycle count from the
sensor clock.
- `sensor_clock_cycles_to_ns()` to convert cycles to nanoseconds using
the clock's frequency.
The implementation supports both system clocks and external clocks
defined in the device tree, making the sensor clock integration more
flexible for various sensor use cases.

The driver now does not wait for the completion of a measurement
in the submit function.
Instead it schedule the fetch and the completion of the
submission queue entry as delayed work to the system work queue.

Inform the executor of a submissions completion with -ENOMEM
if the size of the workq is not big enough.

The integer return of sensor_submit should be void as the call is
asynchronous and the response is meant to be delivered using RTIO APIs
signaling that the submission completed with error or success.
Change the function signature to void and fix all uses of the submit
API, fixing some bugs in the process.

Decoder api was not defined and lead to build error
if it is used in userland.
Fix that by adding necessary DT_DRV_COMPAT #define
in akm09918c sensor decoder.

Use a structured channel specifier rather than a single enum when
specifying channels to read in the new read/decoder API.
Replaces usages of a seperate channel and channel_index parameter
where previously used with a struct sensor_chan_spec.
