Bluetooth: ISO: Add function to get info of ISO channel

Browse source 
The application may want to want the type of an
ISO channel, and take action based on what the type is.

It has been implemented as a get_info to be
consistent with other get_info functions in the
Bluetooth subsystem.

The bt_iso_info struct can be expanded with more information
later as required.
