The struct basically only had a pointer to
bt_iso_chan_path as well as duplicating the pid and
the direction.
The commit removes the struct as it was more confusing than helpful,
and instead use the PID for the bt_iso_chan_path and
supply the direction as a argument instead.

A recent change broke the fallback to using a simple
HCI data path configuration in case that the application
does not provide a data path.
This commit fixes that issue, while retaining the
intended update from the change that broke the fallback,
as well as making the code a bit easier to read
and more documented.

There are two simmilar functions for unsubscribing from GATT handles.
- `gatt_sub_remove`, which is called on disconnect for every
subscription will free the `subscriptions` entry when the entry
represents no subscriptions.
- `bt_gatt_unsubscribe`, called by the application, which forgets to
free the `subscriptions` entry.
If all subscriptions grouped in a `subscriptions` entry are removed
using `bt_gatt_unsubscribe` before disconnect, there are no
subscriptions left to call `gatt_sub_remove` on. The `subscriptions`
entry is then never freed.
The above results in a resource leak of a `subscriptions` entry.
This fix makes explicit and enforces the invariant that there should not
be entries in `subscriptions` with an empty subscription list.

When the application sets more than 251 bytes of advertising data,
the data is sent over multiple HCI commands.
This is only allowed if the advertiser is not running
as defined by the HCI specification.
The data is sent to the controller one AD-field at the time.
If an AD-field is larger than BT_HCI_LE_EXT_ADV_FRAG_MAX_LEN,
the data is split over two commands.
This introduces some additional complexity.

Instead of disconnecting ISO channels on ACL,
we put them in a non-connected state, and wait for
the ISO disconnect events.
This ensure that the controller has free'd the
ISO channels when the iso disconnect callbacks
are received. It will thus be possible to e.g.
terminate the CIG on the ISO disconnect callback.

When an ISO channel is disconnect on the central, it is
not deallocated, but merely disconnected. This is because,
as per the HCI spec, the CIS handle lives on in the CIG.
Instead of unref'ing the bt_conn to 0, we simply put the
channel and connection in the disconnected state.
This also fixes a few missing returns for
terminating a CIG.

The HCI spec defines the BIS index range as starting from
index 0x01. We had previously implemented it such that it
starts from 0x00, and then simply adding 1 to the index
when sending over HCI. However, this may cause issue with
other HCI, or other SIG defined specification, commands
and events, and thus it is probably simpler if we just
use the HCI defined range.
This commit disallows BIT(0) (representing the BIS
index 0x00) to be set, and removes the addition
of 1 when sending over HCI.
