Changes the modem_context_sprint_ip addr to write into a provided

When creating a socket, all of the registered socket implementation are
processed in a sequence, allowing to find appropriate socket
implementation for specified family/type/protocol. So far however,
the order of processing was not clearly defined, leaving ambiguity if
multiple implmentations supported the same set of parameters.
Fix this, by registering socket priority along with implementation. This
makes the processing order of particular socket implementations
explicit, giving more flexibility to the user, for example when it's
neeed to prioritze one implementation over another if they support the
same set of parameters.

Add support for Quectel modem in gsm_ppp modem driver.
The CMUX cmd is based on MUX application notes v1.0(2020-09-22)

As the gsm_ppp doesn't do power control, it is required to power

Fix power-save-mode (PSM) operation.
When in PSM, do not bring the networking interface down
when an out-of-coverage event occurs.
When PSM goes into hibernate, this will cause an
out-of-coverage event to occur, even though the device
still has access to service.
Keeping the networking interface in the up state
allows an app to send data whenever it needs to.

The difference between low power and suspend states is a thin blur line
that is is not clear and most drivers have used indistinctly. This patch
converges to the usage of the suspend state for low power, since
contrary to the low power state, it is used by both system and runtime
device PM. The low power state is still kept, but its future is unclear
and needs some discussion.

There are currently modem_cmd_send() and modem_cmd_send_nolock()
functions, each with slightly different behavior regarding acquiring (or
not) sem_tx_lock. Introduce a generic function that will allow caller to
select behavior using flags.
While at it, add possibility to disable setting and unsetting command
handlers. This will be useful in situations when there are multiple
replies expected one after the other coming as a response to single
command. This is the case for example with ESP-AT driver, which expects
following data as response to AT+CIPSEND command:
OK
>
where 'OK' is handled by static CMD_RESP (so releasing response
semaphore right away), while '>' is handled by dynamic
CMD_HANDLER (which is releasing another semaphore). Keeping command
handlers in place allows to receive '>' without race condition because
of small period of time where command handlers are not set.
Convert modem_cmd_send_nolock() and modem_cmd_send() to static inline
functions, as they are just a specific invocation of
modem_cmd_send_ext() function.
