Update central multilink sample to use continuous scanning
to speed up connection setup.
Update peripheral identity sample to be configurable for
bsim testing as multiple devices with configurable count
of supported connections.

The `type` parameter of `struct bt_le_scan_param` is documented as
taking a `BT_LE_SCAN_TYPE_*` value, not a `BT_HCI_LE_SCAN_*` value.
In practice this makes no difference as the values are defined as the
same integer, but does result in `<zephyr/bluetooth/hci.h>` not needing
to be included.

When the Bluetooth central samples in an open air environment
it is very likely that there are multiple devices nearby with
a received signal strength stronger than -70 dBm.
To avoid connecting to the wrong device, make the check stricter.
For tests using those samples, the NtNcable attenuation is changed
from the default 60 dBm to 40 dBm to satisfy the new requirement.

As both C and C++ standards require applications running under an OS to
return 'int', adapt that for Zephyr to align with those standard. This also
eliminates errors when building with clang when not using -ffreestanding,
and reduces the need for compiler flags to silence warnings for both clang
and gcc.
Most of these changes were automated using coccinelle with the following
script:
@@
@@
- void
+ int
main(...) {
...
- return;
+ return 0;
...
}
Approximately 40 files had to be edited by hand as coccinelle was unable to
fix them.

The sample was only willing to connect if the pair RSSI level
was over -35dBm. That is ok when testing physically keeping
devices at less than 1 meter from each other.
But in CI we test with a default attenuation of 60dB between
devices and the Tx power is 0dBm.
Which causes the tests based on this sample to fail.

As of today <zephyr/zephyr.h> is 100% equivalent to <zephyr/kernel.h>.
This patch proposes to then include <zephyr/kernel.h> instead of
<zephyr/zephyr.h> since it is more clear that you are including the
Kernel APIs and (probably) nothing else. <zephyr/zephyr.h> sounds like a
catch-all header that may be confusing. Most applications need to
include a bunch of other things to compile, e.g. driver headers or
subsystem headers like BT, logging, etc.
The idea of a catch-all header in Zephyr is probably not feasible
anyway. Reason is that Zephyr is not a library, like it could be for
example `libpython`. Zephyr provides many utilities nowadays: a kernel,
drivers, subsystems, etc and things will likely grow. A catch-all header
would be massive, difficult to keep up-to-date. It is also likely that
an application will only build a small subset. Note that subsystem-level
headers may use a catch-all approach to make things easier, though.
NOTE: This patch is **NOT** removing the header, just removing its usage
in-tree. I'd advocate for its deprecation (add a #warning on it), but I
understand many people will have concerns.

In order to bring consistency in-tree, migrate all samples to the use
the new prefix <zephyr/...>. Note that the conversion has been scripted:
```python
from pathlib import Path

for p in Path(".").glob("samples/**/*"):
if not p.is_file() or p.suffix and p.suffix[1:] not in EXTENSIONS:
continue
content = ""
with open(p) as f:
for line in f:
m = re.match(r"^(.*)#include <(.*)>(.*)$", line)
if (m and
not m.group(2).startswith("zephyr/") and
(Path(".") / "include" / "zephyr" / m.group(2)).exists()):
content += (
m.group(1) +
"#include <zephyr/" + m.group(2) +">" +
m.group(3) + "\n"
)
else:
content += line
with open(p, "w") as f:
f.write(content)
