Adds a generic function that will count the number of bits set in
a value.
It uses POPCOUNT (e.g. __builtin_popcount for GCC) if available,
or else it will use Brian Kernighan’s Algorithm to count bits.
POPCOUNT will likely always support unsigned ints, but the function
was implemented to use it with uint8_t for the sake of simplicity
and compatibility with Brian Kernighan’s Algorithm.
A generic solution was chosen rather than a macro/function per
type (e.g. uint8_t, uint16_t, etc.) as that is easier to maintain
and also supports array types (e.g. counting the number of bits
in 128 or 256 octet arrays).

Add a function `bt_br_bond_exists()` to check if the address of the
classic device has been bonded.

The API has not changed since it was introduced so should no longer be

Improve naming of the scheduler and call it what it is: simple. Using
'dumb' for the default scheduler algorithm in Zephyr is a bad idea.

Some GATT services and profiles define specific behavior
based on whether the remote device is bonded or not.
The internal function, bt_addr_le_is_bonded, is the
only function to do this, but it was kept internal,
and could thus not be used for those services
without including hci_core.h.
The function has been moved to the public API
so that application can determine if a remote
address is bonded or not, and has been renamed
to not use the bt_addr namespace, but rather the
bt_le.

Add entry for the removal of the deprecated net_buf_put(), net_buf_get()
API functions, and the deprecated zephyr/net/buf.h header location.

Add a selection of interval values that are suitable for BAP,
which will allow better coexistence between ISO and ACL,
for both broadcast and unicast. Some of these are defined
by the BAP spec, and some are defined by Zephyr, since they
do have a suggested value from BAP.
Samples and tests have been updated to use these new values.
Peripheral samples have also been updated with
CONFIG_BT_GAP_AUTO_UPDATE_CONN_PARAMS so that the connection
parameters from the centrals aren't updated to something else
shortly after.
The shell has also been updated to use the LE Audio (BAP) values
if audio is enabled, and the audio.conf file has disabled automatic
updating of the connection parameters as the peripheral, as we rarely
(if ever) want to do that.
Due to the connection interval change, CI hit an issue
with test_bass_broadcast_code in test_main_client_sync, where
the reading of the long receive state did not finish before we
attempted to do another procedure, so the function was updated to have
a retry.

The function supports reading multiple controller-based values.
It is effectively a copy of struct bt_dev_le but in a more
application-oriented definition.
It was chosen to keep the features as an array rather than a
64-bit value, as the comparison macros work on arrays and that
there already exists new bits > 64 in the core spec which is not
yet supported by Zephyr.
It is being smoke tested in a generic GATT client test,
as the individual values may depend on several Kconfig options.
