This offloads the getaddrinfo() socket operation to the
simplelink WiFi driver, via a socket_offload hook.
This was validated using http_get on cc3220sf_launchxl.
Also implements freeaddrinfo().

Previously, '\n' in LOG_DBG statements were added to
improve readability, by ensuring IP address weren't printed
across typical console terminal line boundaries.
But with the logging updates, '\n' is no longer
getting automatically expanded to \r\n, and a new timestamp
is automatically added, throwing off attempts at alignment.
This patch finally just removes the '\n''s from the log messages,
and cuts a few longer messages into separate messages.

Previously, the NWP (Network Coprocessor) was configured during
simplelink_init().
Since the SimpleLink "FastConnect" feature was added,
meaning an automatic reconnect can occur at this time, this
results in early callbacks into the network stack
before it was fully initialized, resulting in a NULL iface
ptr being sent in as argument.
Now, for safety, the NWP startup is moved later to iface_init,
where it more logically belongs.

The commit 8592501828
("net: Remove s_addr/s6_addr defines from in_addr/in6_addr")
did a (welcomed) removal of a #define s_addr for which the SimpleLink
SDK was checking, breaking the socket_offload driver build.
This patch fixes the driver to work with this new, better
s_addr symbol definition.

If the SimpleLink WiFi driver is configured, and socket offload
enabled, this revectors the Zephyr BSD socket APIs to the SimpleLink
WiFi host driver BSD socket APIs, providing a
direct offload of the TCP/IP stack to the CC3220SF network
coprocessor.

This enables the cc3220sf_launchxl to automatically
reconnect to the last good known access point (AP).
This method avoids the need to:
- perform a wifi scan for access points on bootup (saving power);
- include hard-coded SSID/passwords in the wifi application.
- include the wifi shell in the wifi application.
- rely on more complex provisioning methods;

The wifi_winc1500 driver's socket id is stored in
net_context->user_data, which may be overwritten later at
the socket layer, which also uses the net_context->user_data
field to store socket flags.
This patch introduces a dedicated offload_context field
for use by offload drivers, and updates the wifi_winc1500 offload
driver to use this field instead of user_data.
Fixes#8820

Bool symbols implicitly default to 'n'.
A 'default n' can make sense e.g. in a Kconfig.defconfig file, if you
want to override a 'default y' on the base definition of the symbol. It
isn't used like that on any of these symbols though, and is
inconsistent.
This will make the auto-generated Kconfig documentation have "No
defaults. Implicitly defaults to n." as well, which is clearer than
'default n if ...'

Exposing connect, disconnect and scan for now.
In case the iface is an instance of a WiFi offload device, the way it
manages scanning, connecting and disconnecting will be specific to that
device (not the mgmt interface obviously). In such case the device will
have to export relevantly a dedicated bunch of function to serve the
mgmt interface in a generic way.
