bd7a2fc395 Bluetooth: host: Change directed advertising to privacy-enabled peer
Change the advertising option that controls if the directed advertiser
will use an RPA or the identity address of the peer for the initiator
address.
This option currently has two issues:
 - It behaves differently if the privacy feature has been enabled,
   which can be confusing for application to use.
 - It cannot start a directed advertiser towards a peer that is not
   privacy-enabled and has distributed an IRK.

This commit includes the following changes:
 - When privacy has been enabled in order to advertise towards a
   privacy-enabled peer the BT_LE_ADV_OPT_DIR_ADDR_RPA option must now
   be set (same as when privacy has been disabled).
 - It is now possible to start a directed advertiser using the identity
   address of the peer when privacy-enabled.
 - When privacy has been enabled the advertising option combination
   of using the local identity address and an RPA as the initiator
   address is now disallowed and will return an error code.
   This is done because this combination did not actually work and would
   have used the identity address of the peer instead.
 - If the controller does not support controller-based privacy then
   using the option BT_LE_ADV_OPT_DIR_ADDR_RPA will return ENOTSUP
   because this behavior cannot be done with host-based privacy.

ffab099eb9 Bluetooth: add destroy callback to indication
Adds a `destroy` callback to the `struct bt_gatt_indicate_params` which
is used to signify to the application that the indication operation has
completed and the struct instance can be freed/destroyed.

This is required as the number of indication value callbacks that will
be triggered is not known by the caller when the `conn` parameter is
`NULL`.

Tracking when this callback should be run is mananged by a private
reference counter inside the struct.

170f17e0e7 Bluetooth: indication callback signature update
Update the signature of the `bt_gatt_indicate_func_t` callback type by
replacing the attr pointer with a pointer to the
`bt_gatt_indicate_params` struct that was used to start the indication.

This allows the callback to free the `bt_gatt_indicate_params` instance
if it was allocated from storage, while still allowing the
`bt_gatt_attr` value to be accessed through `params->attr`.

Allocating the `bt_gatt_indicate_params` instance from storage is
desirable as multiple indications can be queued, however each instance
must be valid until the callback is run.

Implements API update from #29357

f8956cfbc7 Bluetooth: L2CAP: Enable L2CAP dynamic channels without Enhanced CBFC
Allow application to enable L2CAP dynamic channels without support
for Enhanced Credit Based Flow Control (CBFC).

Since these are separate features in the qualification it should
be possible to qualify L2CAP connection oriented channels without
also having to qualify L2CAP enhanced credit based flow control.

The L2CAP/LE/REJ/BI-02-C conformance test will fail when enhanced CBFC
has not been selected in the ICS.

The lower tester expects that since the Enhanced CBFC is not supported,
the command L2CAP_CREDIT_BASED_CONNECTION_REQ should be met with an
L2CAP_COMMAND_REJECT_RSP and not an L2CAP_CREDIT_BASED_CONNECTION_RSP.

77b11d6b0c Bluetooth: host: Move auto-initiation of peripheral conn param update
Move auto-initiation of the peripheral connection parameter update,
this handling would only submit the delayed work with the timeout once
all other auto initiated procedures had completed. This behavior means
that the delay would not be set on when the connection was established
but instead relative to the previous procedures.
Based on the connection interval used, the instant(s) used, and the
number of auto procedures this delay becomes indeterminate.

Submit the work once connected, the constraint that existed in the
zephyr link layer earlier about requesting only one control procedure
at a time has been removed.

This also brings all the handling of the timeout work to the connection
state handling, which makes it easier to track this behavior in code.
