The ISO security implementation works by verifying
against the acl (bt_conn) sec_level field. The
bt_conn sec_level field is only available
if CONFIG_BT_SMP is enabled, so this commit
adds guards for all ISO security checks as well.

Add two new Kconfigs: BT_ISO_CENTRAL and BT_ISO_PERIPHERAL
that is used to do central or peripheral only builds,
similar to the BT_CENTRAL or BT_PERIPHERAL Kconfigs.

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
import re
EXTENSIONS = ("c", "h", "cpp", "rst")
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)
```

Add reference to specific CONFIG_BT_CTLR_ Kconfig options
for the ISO samples. This is due to the fact that ISO
isn't fully supported in the Zephyr controller yet, and
won't be enabled by default for a while yet.

Add a new struct that provides information to the upper
layer when accepting an connected isochronous stream.
The CIG ID and CIS ID makes it possible for the upper layer
to determine which ISO channels are "together" in a group.

Update the name of the bt_conn pointers to make it clear
whether the connection pointers are ACL or ISO connections.

Move to CMake 3.20.0.
At the Toolchain WG it was decided to move to CMake 3.20.0.
The main reason for increasing CMake version is better toolchain
support.
Better toolchain support is added in the following CMake versions:
- armclang, CMake 3.15
- Intel oneAPI, CMake 3.20
- IAR, CMake 3.15 and 3.20

Add a new Kconfig option, BT_ISO_UNICAST, to make it possible
either configure unicast only, broadcast only or both.
This results in some code being moved, but not modified, and
should not effect anything.

The sequence number is needed in the appliaction layer to detect lost
packets in the ISO stream in cases where the timestamp is not included.
(Sequence number is mandatory to include where timestamp is optional).
The API for the public metadata have been moved to a public header file.
As the size of the ISO meta data exceeds the default 4 octets net_buf
user_data the public ISO metadata have been moved into a seperate array.
The internal metadata is still stored in net_buf user_data.
This also fixed the user_data overflow on 32 bit systems, caused by
writing the ts into user_data on index 4 to 7, which is outside the 4
allocated bytes.

The sample would consequently try to print invalid data
the offset into the data was incorrect calculated to
always be at the end of the data, instead of at the
end of the data minus an offset.
