35897ee66c Bluetooth: Kconfig: Get rid of BT_HCI_VS_EVT
Enabling vendor-specific extensions also implies support for vendor
events, so a separate Kconfig option for that is unnecessary.

One small additional thing this requires is the use of the
__maybe_unused annotation, since there's no-longer a single Kconfig
option that the controller hci.c can use to know that the vendor event
helper symbols are needed.

18c23daee3 Bluetooth: Kconfig: Merge BT_HCI_VS_EXT into BT_HCI_VS
The naming of these two options was problematic, since it's both of them
are about vendor extensions, even though one has _EXT in the name and
the other doesn't. Just merge one option into the other. This has a
slight overhead on the controller side of enabling some more vendor
features if BT_HCI_VS is enabled, but that should hopefully be
acceptable.

7f82b6a219 Bluetooth: controller: Prevent invalid compiler code reordering
In ull_disable, it is imperative that the callback is set up before a
second reference counter check, otherwise it may happen that an LLL done
event has already passed when the disable callback and semaphore is
assigned.

This causes the HCI thread to wait until timeout and assert after
ull_ticker_stop_with_mark.

For certain compilers, due to compiler optimizations, it can be seen
from the assembler code that the callback is assigned after the second
reference counter check.

By adding memory barriers, the code correctly reorders code to the
expected sequence.

171363501a Bluetooth: Move bt_hci_evt_get_flags out of hci_driver.h
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.

b91728619c Bluetooth: host: remove CONFIG_BT_RECV_BLOCKING
This config selects a variant of the HCI driver interface that spills
out host internals unto the drivers and even the Zephyr controller. It
will now be removed in favor of driver interfaces that hide the
internals of the host.

The new default is `CONFIG_BT_RECV_WORKQ_BT`.

Any references to the removed kconfig are refactored out.

Any out-of-tree driver using the removed interface can be easily adapted
by copying the following implementations into the driver as private
functions:

 - `hci_driver.h:BT_HCI_EVT_FLAG_RECV_PRIO`
 - `hci_driver.h:BT_HCI_EVT_FLAG_RECV`
 - `hci_driver.h:bt_hci_evt_get_flags`
 - `hci_raw.c:bt_recv_prio`

In combination these symbols function as a interface adapter. These
symbols will be removed in this PR in subsequent commits.
