Add the option for a unique numeric identifiers to be attached to a zbus channel. This identifier can then be used to lookup the channel structure at runtime. This is useful in two situations (that I can immediately think of). Firstly for external interaction, i.e a text shell or remote procedure calls. The current state of a channel can be queried by an ID that never changes, as opposed to the external entity needing to know the exact memory address of the channel for a given application binary. Secondly for integrating with dynamically loaded extensions (llext). These extensions can hook into the existing data streams without each individual channel needing to be exported and visible to the loader. Signed-off-by: Jordan Yates <jordan@embeint.com>
