  1. sensors: Add streaming APIs 

    Introduce a streaming API that uses the same data path as the async API.

This includes features to the decoder:
* Checking if triggers are present

Adding streaming features built ontop of existing triggers:
* Adding 3 operations to be done on a trigger
  * include - include the data with the trigger information
  * nop - do nothing
  * drop - drop the data (flush)
* Add a new sensor_stream() API to mirror sensor_read() but add an
optional handler to be able to cancel the stream.

  3. sensors: convert fifo_wm to batch_dur 

    Having a % FIFO watermark isn't very useful as it doesn't convey how long
the SoC can sleep (or do other work) while batching sensor data. Convert
the attribute to a batch duration using ticks. Currently the ticks are
in system ticks, but eventually when an external clock is attached to
the sensor it will be in the external clock's ticks.
