Rodrigo Peixoto 4d80338132 samples: zbus: fix samples to work with iterable sections observers
Replace the `CONFIG_ZBUS_RUNTIME_OBSERVERS_POOL_SIZE` with the
`CONFIG_ZBUS_RUNTIME_OBSERVERS` and add the heap. Add user_data to hello
world sample iterator functions.

Runtime observer registration sample
####################################

Overview
********
The sample illustrates a way of using the runtime observer registration feature. The developer can understand how to use static and runtime observer registration with this sample.

In this sample, we have the threads producer and consumer. In the middle of the communication, we have the filter responsible for filtering the data generated by the producer. In a loop, the code activates the filter. After 5 seconds, the filter is disabled, and the filter bypass is enabled. At last, 5 seconds later, the filter bypass is disabled, and the loop repeats everything.

Building and Running
********************

This project outputs to the console.  It can be built and executed
on QEMU as follows:

.. zephyr-app-commands::
   :zephyr-app: samples/subsys/zbus/runtime_obs_registration
   :host-os: unix
   :board: qemu_x86
   :goals: run
