Iulia Tanasescu 6a42e9bfd1 Bluetooth: ISO: Support multiple BIGs
This adds support for creating multiple BIGs. According to
spec, each BIG shall have an unique handle, and each BIG should
be associated with a different advertising handle. Otherwise,
the LE Create BIG command will fail, with error code
Command Disallowed (for reusing a BIG handle), or
Unknown Advertising Identifier (for reusing an advertising
handle).

The btmon snippet below shows an exercise for creating two BIGs
for the same controller, by opening two isotest instances with
the following command:
    tools/isotest -i hci0 -s 00:00:00:00:00:00
