Allow user to create a kitchen sink pseudo a.k.a any network
interface that one is only able to write to. This might seem
unnecessary, but it is possible to attach virtual network
interfaces on top of this pseudo interface. These virtual
interfaces could then process the data for example for
packet capture purposes.

Add a recv callback to dummy API. After this it is possible to
receive data by a dummy network interface. This is only useful
if one attaches a virtual interface on top of the dummy one.
One such example is the cooked mode capture interface.

The dummy L2 layer does not implement any L2 functionality
but it does not mean that it should not implement start/stop
functions that are called when the related network interface
is brought up or taken down.

In order to bring consistency in-tree, migrate all subsystems code to
the new prefix <zephyr/...>. Note that the conversion has been scripted,
refer to zephyrproject-rtos#45388 for more details.

Create net_l2_send() function which will be called by each L2
sending function so that we can catch all the network packets
that are being sent. Some L2 layers send things a bit differently,
so in those cases call the net_capture_send() directly by the L2
layer.
Add network packet capture call in receive side after the pkt has
been received by the RX queue handler. This avoids calling the
net_capture_send() from ISR context.

It is possible that the device driver API pointer is null.
For example if the device driver returns an error, the device
code will make the API pointer NULL so that the API would not
be used. This can cause errors in networking code where we
typically do not check the NULL value.

Update the files which contain no license information with the
'Apache-2.0' SPDX license identifier. Many source files in the tree are
missing licensing information, which makes it harder for compliance
tools to determine the correct license.
By default all files without license information are under the default
license of Zephyr, which is Apache version 2.

Remove network specific default and max log level setting
and start to use the zephyr logging values for those.
Remove LOG_MODULE_REGISTER() from net_core.h and place the
calls into .c files. This is done in order to avoid weird
compiler errors in some cases and to make the code look similar
as other subsystems.

Instead of one global log level option and one on/off boolean
config option / module, this commit creates one log level option
for each module. This simplifies the logging as it is now possible
to enable different level of debugging output for each network
module individually.
The commit also converts the code to use the new logger
instead of the old sys_log.

*_ll_src/*_ll_dst/*_ll_swap/*_ll_if were not self explanatory, ll
meaning "link layer" it's ambiguous what the names meant.
Changing to:
*_lladdr_src/*_lladdr_dst/*_lladdr_swap/*_lladdr_if to fix this.

No need to keep technologies in main L2 directory so for consistency
create a directory for each of them and place each L2 component to
relevant L2 directory.
