Add a new API function zbus_chan_from_name() that allows retrieving a
zbus channel by its name string. This complements the existing
zbus_chan_from_id() function and provides more flexibility for channel
lookup operations.
The implementation is conditionally compiled when CONFIG_ZBUS_CHANNEL_NAME
is enabled, ensuring it's only available when channel names are configured
in the system.
