This adds HCI driver which enables communication with CMAC core on
Renesas SmartBond DA1469x series. The CMAC core is running an Apache
NimBLE controller binary and uses shared memory for communcation via
mailboxes.

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.

In the case that there are no more ISO buffers left,
"No available ISO buffers" is logged. However, given the
nature of ISO where we are (very) likely to get additional ISO
very soon after (typically every 7.5 or 10ms for audio),
this will get logged a lot, and the logging may in some
cases actually prevent the application from handling and
freeing existng buffers due to the immense logging,
which may make this (minor) issue into a blocking issue.
This is fixed by reducing the logging to the first
occurence, and then only every 100 afterwards, which has
shown to reduce the risk of this effectively blocking
the application.

A payload size of 0xFF is valid and should not be a reason to keep
looping for more headers. The complete reqiurement is now:
```
header_slave[STATUS_HEADER_READY] == READY_NOW &&
header_slave[STATUS_HEADER_TOREAD] > 0
```
This fixes events being dropped when the payload size is 255.

Enforcing the peer's behavior is not strictly necessary. All the host
should do is make sure it is resilient to a spec-violating peer.
Moreover, a growing number of platforms were disabling the check, as the
spec allows "batching" HCI num complete packets events, stalling ATT RX.

The zephyr bluetooth stack expects the controller to know its public
address, if any. At least for BlueNRG, the public address is forgotten with
every reset/power cycle, so there needs to be a way to set it from within
zephyr. This is accomplished using the `Aci_Hal_Write_Config_Data` HCI
command, as described in PM0237.
