It has been observed that using a CMUX max frame size of 127
causes FCS errors; smaller or larger works. This commit sets the max
frame size to the modem's default value.

Introduced `MODEM_CELLULAR_DEFINE_INSTANCE` macro to streamline
the definition and initialization of modem cellular instances.
This macro enables passing parameters that vary among modems, including:
`power_pulse_duration_ms`, `reset_pulse_duration_ms`, `startup_time_ms`,
`shutdown_time_ms`, `autostarts`, `init_chat_script`, `dial_chat_script`
and `periodic_chat_script`.
This will reduce the number of redundant lines in the code, aiming for
improved maintainability.

The supported modems don't have the same number or assignment
of DLCI channels. For example, the NRF91_SLM only has DLCI
channel 3 assigned to GNSS tunneling, where the ublox sara r5
has DLCI 3 assigned to an additional AT channel, and DLCI 4
assigned to GNSS tunneling.
This commit updates the creation and assignment of DLCI
channels and pipelinks to match the capabilties of each modem.

The modem_cellular.c driver now uses a common script to get
signal strenght, which is run on demand. This is more efficient
than polling it, and simpler since every modem doesn't have to
define their own variant of the script.
Additionally, the CSQ handler now stores the "raw" rssi value
returned from AT+CSQ to be parsed by the cellular_modem_get_signal
implementation.

This commit adds a timeout of 300ms to the generic (gsm_ppp) init
chat script. This delay is required for some modems (discovered on
a Telit ME910G1-WW) to allow it to enter CMUX mode. Without this
delay, the modem simply refuses to respond to any CMUX commands.

This commit improves the usage of the bus pipe (connected
to UART) to only open it when the modem is actually
powered and ready, not when leaving the idle state. This
ensures the pipe is flushed before sending the init script,
and re-enables the UART driver if it is disabled due to
errors.
While building a test platform based on the nRF9160 and a
Quectel BG95, it was discovered that the nRF9160 correctly
throws UART errors if the RX is enabled while the UART RX
line is low (which was due to the modem being powered
down).
The improvements should also help help remove the
"<wrn> modem_chat: receive buffer overrun" warning which
would occur during startup as the pipe was opened, but
nothing was receiving the data, causing the buffer to
overflow.

The added cellular modem driver is a naive driver, which
shall serve as a template for implementing tailored
drivers for modems like the UBLOX-R4. It uses only
generic at commands, described in 3gpp, and protocols,
like CMUX and PPP.
A binding for the BG95 has been added, which replaces
the quectel,bg9x. This is neccesary since the BG95 does
not have a usable reset pin, the reset and powerkey are
internally connected to each other.
