This change decouples the IEEE 802.15.4 (L2) layer from all IPv6 (L3)
concerns.
Applications may now choose to set CONFIG_NET_6LO=n and
CONFIG_NET_L2_IEEE802154=y at the same time.
Setting CONFIG_NET_6LO=n will build a vanilla IEEE 802.15.4-2006 specs
compliant L2 layer without any reference to 6LoWPAN or IPv6. This allows
application developers to design custom non-IP protocols on top of
IEEE 802.15.4-2006 and thereby makes the L2 layer much more re-usable.
Fixes#48585.

The packet socket implementation did not fill the address structure
provided by the application. This commit fixes this.
Note, that the implementation needs to cover two cases: SOCK_RAW and
SOCK_DGRAM. In the first case, the information is extracted directly
from the L2 header (curently only Ethernet supported). In latter case,
the header is already removed from the packet as the L2 has already
processed the packet, so the information is obtained from the net_pkt
structure.

This commit removes the resource pointer NULL check inside the resource
enumeration loop of the `coap_well_known_core_get` function because the
expression `(resource + 1)` will never evaluate to NULL (aka. 0).
This fixes the "comparison will always evaluate as ‘true’ for the
pointer operand" warning generated by the GCC 12.

There is a potential, corner case scenario, where a deadlock can occur
between TCP and socket layers, when both ends of the connection transmit
data.
The scenario is as follows:
* Both ends of the connection transmit data,
* Zephyr side send() call gets blocked due to filing the TX window
* The next incoming packet is data packet, not updating the RX window
on the peer side or acknowledging new data. The TCP layer will
attepmt to notify the new data to the socket layer, by calling the
registered callback. This will block the RX thread processing the TCP
layer, as the socket mutex is already acquired by the blocked send()
call.
* No further packets are processed until the socket mutex is freed,
which does not happen as the only way to unblock send() is process
a new ACK, either updating window size or a acknowledging data.
The connection stalls until send() times out.
The deadlock is not permament, as both threads get unlocked once send()
times out. It effectively breaks the active connection though.
Fix this, by unlocking the socket mutex for the time the send() call is
idle. Once the TCP layer notifies that the window is available again,
the mutex is acquired back.
