The HCI receive path has a delay between reading the header and payload
from the controller to give the controller time to setup the SPI
peripheral for the next transaction. Add the same delay on the transmit
path for the same reasons.

The existing driver and sample:
- drivers/bluetooth/hci/rpmsg
- samples/bluetooth/hci_rpmsg
are no longer correctly named, since they now use the IPC subsystem to
send and receive data. The IPC subsystem can use RPMsg as a transport,
but that is one of several selectable backends.
I initially wanted to deprecated both the BT_RPMSG Kconfig option as
well as the zephyr,bt-hci-rpmsg-ipc chosen node in Devicetree. However,
this proved to be undoable in the case of the Kconfig option. This is
because it's a choice option, and those have special behavior. In
particular, the only practical way to deprecate would've been to keep
the old Kconfig option outside the choice (much like it's done in this
commit) but then also add a 'depends on !BT_RPMSG' on each of the
remaining choice symbols *except* on the new BT_HCI_IPC one. This, however,
only works correctly for .conf files. If a board instead sets the
default BT_HCI_BUS_TYPE in the Kconfig.defconfig file then the Kconfig
tree parsing would fail, because it'd try to set it to a value
(BT_RPMSG) that is no longer part of the choice.

Don't re-use the `rxmsg` buffer in the `bt_spi_send` function. This
buffer is still used by the RX thread after releasing the SPI semaphore.
The current re-use can result in buffer corruption if the RX thread is
swapped out as a result of the `k_sem_give`.
Moving the semaphore release later can result in deadlocks due to
buffer allocation being performed while holding the semaphore, so
instead just eliminate the re-use entirely.

The previous commit added the documentation on `bt_recv` stemming from

Currently, HCI packet handling does not consider the BT_RECV_CONTEXT
choice selection. It calls bt_recv() and bt_recv_prio() only depending
on the HCI packet type and event flags.
However, for selections other than BT_RECV_BLOCKING, the "HCI driver
shall not call bt_recv_prio()". Fix that by only calling bt_recv_prio()
when CONFIG_BT_RECV_BLOCKING is enabled.

Add a small delay between reading the transport header and reading the
HCI data. Failing to do so on a nRF9160<->nRF52832 link was reliably
resulting in the nRF9160 trying to read data before the nRF52832 had
set up the SPI transaction, resulting in the host reading a buffer full
of 0x00 and having to run the entire read result again.
Transceiving a 10 byte packet takes at least 31uS, while 100 byte
packets are around 150uS (duration of `spi_transceive` call). Waiting
1 tick to eliminate the need for most retransmissions is a valid
tradeoff.

Don't wait for the IRQ line to be de-asserted in `bt_spi_send`. As this
function can be called by the RX processing thread, the previous
behaviour could cause deadlocks under heavy load:
* SPI RX thread starts blocking on `bt_buf_get_evt` due to load
* BT controller generates another event, asserting the IRQ line
* RX processing thread calls `bt_spi_send` in reponse to event
* RX processing thread blocks forever on the removed condition
There is no need to attempt to rate-limit how often `bt_spi_send` is
called to allow the RX thread to run. If the bus is so congested that
there is no remaining capacity, prioritising RX over TX is not going to
improve the situation.

Use level triggered interrupts instead of edge triggered interrupts to
make it impossible for the interrupt line to be active without the RX
thread attempting to read pending data.
This fixes a race condition for re-enabling the interrupt in edge
triggered mode, where `gpio_pin_interrupt_configure_dt` is not called
before the controller re-asserts the interrupt line.
As a result the controller can be reset before booting the RX thread.

As of today it is not possible to use SPI dt-spec macros in C++,
something known and documented. The main reason is because `cs` property
is initialized using a compound literal, something not supported in C++.
This PR takes another approach, that is to not make `cs` a pointer but a
struct member. This way, we can perform a regular initialization, at the
cost of using extra memory for unused delay/pin/flags if `cs` is not
used.

The init infrastructure, found in `init.h`, is currently used by:
- `SYS_INIT`: to call functions before `main`
- `DEVICE_*`: to initialize devices
They are all sorted according to an initialization level + a priority.
`SYS_INIT` calls are really orthogonal to devices, however, the required
function signature requires a `const struct device *dev` as a first
argument. The only reason for that is because the same init machinery is
used by devices, so we have something like:
```c
struct init_entry {
int (*init)(const struct device *dev);
/* only set by DEVICE_*, otherwise NULL */
const struct device *dev;
}
```
As a result, we end up with such weird/ugly pattern:
```c
static int my_init(const struct device *dev)
{
/* always NULL! add ARG_UNUSED to avoid compiler warning */
ARG_UNUSED(dev);
...
}
```
This is really a result of poor internals isolation. This patch proposes
a to make init entries more flexible so that they can accept sytem
initialization calls like this:
```c
static int my_init(void)
{
...
}
```
This is achieved using a union:
```c
union init_function {
/* for SYS_INIT, used when init_entry.dev == NULL */
int (*sys)(void);
/* for DEVICE*, used when init_entry.dev != NULL */
int (*dev)(const struct device *dev);
};
struct init_entry {
/* stores init function (either for SYS_INIT or DEVICE*)
union init_function init_fn;
/* stores device pointer for DEVICE*, NULL for SYS_INIT. Allows
* to know which union entry to call.
*/
const struct device *dev;
}
```
This solution **does not increase ROM usage**, and allows to offer clean
public APIs for both SYS_INIT and DEVICE*. Note that however, init
machinery keeps a coupling with devices.
**NOTE**: This is a breaking change! All `SYS_INIT` functions will need
to be converted to the new signature. See the script offered in the
following commit.
