a8bbe4d1db bluetooth: host: Disallow directed adv options on undirected adv
Previously, if the peer address was not set, the host would
do undirected advertising even if the application applied
options only applicable to directed advertising.

Adding this additional parameter validation reduces the confusion
of application developers when they have configured something wrong.

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.

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.

5b034e103f bluetooth: hci_driver: Add BT_QUIRK_NO_AUTO_DLE
Some controllers do not follow the recommendation of auto-initiating
a data length update if the host writes default data length parameters.

If the controller follows this recommendation, calling
LE Write Suggested Default Data Length command is sufficient
to ensure that the LL will auto-initiate the DLE procedure. Performing
a second procedure is unecessary.

In Core v5.2, Vol 4, Part E, Section 7.8.35:
The HCI_LE_Write_Suggested_Default_Data_Length command allows the
Host to specify its suggested values for the Controller's maximum
transmission number of payload octets and maximum packet
transmission time for packets containing LL Data PDUs to be used
for new connections. The Controller may use smaller or larger values
for connInitialMaxTxOctets and connInitialMaxTxTime based on local
information.

In short, this command sets connInitialMaxTxOctets
and connInitialMaxTxTime.

In Core v5.2, Vol 6, Part B, Section 4.5.10:

For a new connection: connMaxTxOctets shall be set to
connInitialMaxTxOctets and connMaxRxOctets shall be chosen by the
Controller. If either value is not 27 then the Controller should
initiate the Data Length Update Procedure at the earliest practical
opportunity.
