Merges bt_csis_client_discover and
bt_csis_client_discover_sets, as they should be done
together for the discovery procedure from the CSIP
spec.

Rename struct bt_csis_client_set to
struct bt_csis_client_csis_inst, as that is more descriptive
of the actual content of the struct.
This also avoids the confusion about what a "set" is,
which is clearly not a single instance of CSIS
on a single remote server.

Several APIs worked on the bt_csis_client_set struct,
which not only included information about a set, but
also a reference to a specific CSIS instance.
A specialized struct only for the set information
is more useful in those scenarios.

Modify bt_csis_client_get_lock_state to be the Ordered Access
procedure, which means that instead of reading a single lock value
on a single device, it will read the lock value for all
set members supplied in the function, and return true if any
of them is locked, or false otherwise.

Rename bt_csis_client_lock_get to
bt_csis_client_get_lock_state. `get` could be
misunderstood as acquire, i.e. that `get` would
mean that the lock was taken by this device.
The new name should make it more obviously that it
is just a read procedure.

Remove the addr struct from bt_csis_client_set_member as that
was only used by the upper layers and not the CSIS client
itself, and as such should only reside in the
upper layers.

Change how the SIRK is exposed to the upper layers.
The SIRK will always be the unencrypted 16 octet
SIRK now, instead of a struct.
This not only allows us to avoid having a
__packed struct in the API, but also gives a better
API as we don't expose encrypted data to the upper layers.

Remove the error code BT_CSIS_ERROR_SIRK_ACCESS_REJECTED
as it no longer exists in the specification.

Refactor the bt_csis_client_lock_get function to use a
pointer to a member and a set instead of a bt_conn
pointer and an index.

Refactor the bt_csis_client_lock_read_cb callback to use
a bt_csis_client_set pointer instead of conn and index.

Refactor bt_csis_client_discover_sets to use the
bt_csis_client_set_member struct instead of a bt_conn.
The bt_csis_client_set_member represents a remote server
(set member), and make it possible to avoid sending indexes
of instances around instead of bt_csis.

Remove the lock and release sets functions, as well
as the discover member function as they have been removed
from the implementation a while ago.

Use the bt_csis_client_set_member struct to store the individual
bt_csis client struct. This way they are exposed to the
client application.

Add an [out] array to the discovery function and
an array to the discovery callback of bt_csis structs.
These should be used instead of bt_conn pointers for
CSIS client.

Move the header file csis.h from the internal location to
the public include directory. This file is supposed to provide
the public API for CSIS and the CSIS client, but is not fully
complete yet.
