the CSIS client now has a ordered access procedure function.
The function implements the procedure as per the CSIP spec,
where it will verify that 1 or more members are unlocked,
and the execture a procedure on each member in ascending
order of rank.
The procedure can be anything (even a non-BT procedure),
and it will be up to the applicaiton to implement
what to do in that.

Having the members array being const causes a lot of
limitations in the implementatation, and was
occasionally even disregarded. Removed to make the
implementation more flexible.

In order to bring consistency in-tree, migrate all subsystems code to
the new prefix <zephyr/...>. Note that the conversion has been scripted,
refer to zephyrproject-rtos#45388 for more details.

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.

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

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

Move the header file csis.h from the internal location to

complete yet.
