Add callbacks to the stream objects that reflects the
state of the isochronous channel. The connected callback
is called when the isochronous channel is connected, and
similarly the disconnected callback is called when it is
disconnected.
There is a special case for unicast, where if the ACL
disconnects first, then we won't get a ISO disconnect
callback. It should be assumed that the isochronous channel
is no longer valid when the BAP stream enters the idle state,
i.e. when the "released" callback is called.
The purpose of the new callbacks is to provide additional
information to the application. Especially the unicast client
can use this to determine when the stream_start function
can be called again, as there can only ever be 1 outstanding
CIS connection request at a time, but there can be multiple
GATT requests.

This adds the expect_bt_bap_stream_ops_released_called function that
takes an array of streams to verify as an argument. It's more versatile
approach than having expect_bt_bap_stream_ops_released_called_twice
erc. functions, that scales bad.
The function ignores the arhument list order, so that the user does not
have to predict the exact order of function calls.

Continue test execution even if assumption failed. This won't break the
test execution prematurely and allow to perform a cleanup.
