OTS requires that indications about state change are sent after
response to ATT Write.
OTS Specification p.4.4.4.: "An OLCP or OACP operation is started
when the ATT Write Response is received from the Object Server as
a result of the Object Client writing an Op Code to a control point
to perform some desired action. The control point operation ends
when the Object Server sends an indication to the Object Client
with the Op Code set to Response Code."

To make it easier to understand the code, the following was done:
- Use INITIATING/ADV for state names that are exclusive to central
or peripheral. Previously it was not necessarily clear that the state
BT_CONN_CONNECTING was for central only by just looking at where
it was used. The terms INITIATING/ADV were used in favor
of central and peripheral as these terms also work for SCO connection
establishment.
- BT_CONN_CONNECTING_SCAN -> BT_CONN_SCAN_BEFORE_INITIATING
to make it more clear that we are not scanning and connecting at
the same time. The new name should make it more clear why we are
scanning - only with the intention to start the initiator later.
- BT_CONN_CONNECTING_AUTO -> BT_CONN_INITIATING_FILTER_LIST.
This makes it clear that this state is something different than
BT_CONN_AUTO_CONNECT.

The following warning is issued by clang:
warning: field within 'struct gatt_chrc' is less aligned than 'union
gatt_chrc::(anonymous at subsys/bluetooth/host/gatt.c:1859:2)' and
is usually due to 'struct gatt_chrc' being packed, which can lead
to unaligned accesses [-Wunaligned-access]
This is due to the fact that the uint16_t uuid field requires 2-byte
alignment but it is not marked as packed. Since the enclosing struct is
indeed packed, the required alignment is not guaranteed and so clang
complains. Fix it by ensuring that the union is marked as packed too.

advertiser option but the original behavior has been reproduced.
The option of the extended advertiser have been updated to be more

`bt adv-create` and `bt adv-param`. The option `name` and `dev-name`

The comment states the reason for this requirement is to detect
violations by a remote peer. The ATT version of this was removed in
ea04fd95f9. TLDR: It's neither possible
for, nor the job of the host to police the remote device.
We remove this requirement to be more flexible about the number of
priority levels in the system, and to avoid the temptation of using
priorities as a synchronization mechanism.

When creating a broadcast sink using the auto scan feature,
the call to bt_le_per_adv_sync_create would use a local
PA sync pointer, instead of one from the per_adv_syncs
array, making it impossible to stop the PA sync afterwards.
This commit modifed the auto_scan so that it properly uses
the per_adv_syncs array, while still assigning the PA sync
in the shell broadcast sink struct.

This commit removes `bt_hci_evt_get_flags`, and the associated flag
symbols. These symbols no longer serve a purpose in the driver interface
after the removal of `bt_recv_prio` from the interface.
The implementation of `bt_hci_evt_get_flags` is distributed to its
still-existing use sites, `hci_core` and the `hci_driver` in the
controller.
The duplication of code is intentional. This is no longer part of any
interface, and the host-developers expect the host copy of the function
to change or dissapear entierly. This will allow the host implementation
to progress without fear of breaking the controller implementation.
