The modem modules cmux module is currently directly coupled to the
presence of specific modems, rather than being selected by drivers
for whatever hardware wants to request the default MTU of 127 bytes.
This commit the makes the device drivers (for now, modem_cellular)
select the symbol, thus decoupling the modem modules from the
presence of any specific device.

Some modems (e.g. Quectel BG95/EG25-G, several SIMCom parts) print
“APP RDY” when the application core is ready. Parse this line and
proceed from AWAIT_POWER_ON immediately, while keeping the existing
startup timeout as a fall-back.

Add optional autostarts boolean to the quectel,bg95 binding and make
MODEM_CELLULAR_DEFINE_INSTANCE() use it through DT_PROP_OR().
Boards that carry a BG95-M3 Mini-PCIe card—or any other variant that
boots at VCC can now declare the property and skip the PWRKEY pulse,
while existing designs continue to behave unchanged.

Quectel BG9x returns only the base model string to AT+CGMR, while
AT+QGMR provides the true firmware build ID, e.g.
AT+CGMR → BG95M3LAR02A03

Fix regression introduced by dormant state, where the
carrier does not get closed when Cellular Modem driver
is suspended.
Signed-off-by: Markus Lassila <markus.lassila@nordicsemi.no>
Previously, it was expected that the modem would immediately
disconnect and close the PPP link, when the network was lost
(+CEREG: 4 is received). Failure to do so, would result in
modem attempting to chat with dlci2 channel, where as cellular
modem driver would drop to dlci1. This would show as dial
script timing out, which would freeze cellular modem driver.
Adding dormant state enables graceful disconnection of PPP-link
when the network is lost. This allows the modems which do
not automatically close with network link loss to close
based on PPP link closure.

Allow configuring MTU for CMUX.
Some AT manual and specification define this as a
frame size. Linux ldattach default to 127 bytes,
3GPP TS 27.010 defaults to 31.
We should limit our CMUX frames to a size that
remote end is capable of handling.
Linux silently drops oversized frames.
Also, remove MODEM_CELLULAR_CMUX_MAX_FRAME_SIZE as
this was only limiting a buffer sizes, and resulted
CMUX frames to be capped to same value.
Use MODEM_CMUX_WORK_BUFFER_SIZE and MODEM_CMUX_MTU instead.
Also rename CONFIG_MODEM_CELLULAR_CHAT_BUFFER_SIZES to
CONFIG_MODEM_CELLULAR_CHAT_BUFFER_SIZE as it is now
only used as a Chat module. DLCI pipes use
CONFIG_MODEM_CMUX_WORK_BUFFER_SIZE.

`+C*REG:` may be received as AT read command answer

Their syntax differs, and even the overall parameter count varies
depending on what `<n>` is used in the `AT+CEREG=` write command.
To handle all cases properly, check the parameter count and
the presence of the `<tac>` parameter (which is a string and
thus begins with `"`) to figure out what is the position of `<stat>`.
