This patch introduces MGMT events for BIGInfo advertising reports, so
that the event can be passed from kernel to userspace.

This patch also adds the sync_handle field to the bt_iso_bcast_qos
structure.

These changes are needed in order to implement the BASS Set Broadcast
Code operation - a BASS Server is required to inspect BIGInfo
advertising reports received from a Broadcast Source, to determine if
the BIG is encrypted or not. The Server is only able to associate a
Broadcast Source with a received BIGInfo report by looking at the
sync_handle field. This is why the sync_handle needs to be available
in the QoS structure, so that it can e retrieved via getsockopt, once
PA sync is established.
