Currently, zbus uses a single global `net_buf`pool to publish messages to msg_subscribers. It would be good to have a way to separate the pools for channels related to critical parts of the systems to avoid publication failure on these particular channels. These channels will not use the global pool. They can set an isolated pool by calling the `zbus_chan_set_msg_sub_pool.` Signed-off-by: Rodrigo Peixoto <rodrigopex@gmail.com>

This configuration enables the developer to change the _ZBUS_ASSERT behavior. When this configuration is

enabled, _ZBUS_ASSERT returns -EFAULT instead of assert. It makes it more straightforward to test invalid
