The UART backend test suite performs 9 iterations of:
1. Open UART backend pipe
2. Transmit 8192 bytes of pseudo random data
3. Receive and validate bytes
4. close UART backend pipe
The test is run on real hardware, with the TX/RX pins
connected to each other to provide loopback functionality.
The test suite has been run on a STM32 and an nRF5340 board.
The test suite tests both the UART interrupt driven and
async APIs.

This commit increases the buffer used for commands
in the control channel within an instance of the
modem_cmux module. The buffer was not large enough to
store an MSC command if the optional break signals
where included. This commit fixes the issue and
updates the test suite to use the max size MSC message.

This commit sets the C/R (command/response) bit when UIH
CMUX frames are sent from the modem_cmux module. This bit
is ignored by some modems like the Quectel BG95, as there
is no defined response to this specific CMUX frame type.
However, other modems, like the TELIT ME910, require the
bit to be set (command). If the bit is not set, the modem
will simply ignore the frame completely.

This PR adds a mechanism to avoid calling open() or close()
on pipes which are already opened or closed respectively.
This optimization can help simplify backends implementing
the modem_pipe API by avoiding duplicated boilerplate code.
The TTY backend test suite has been updated to match the
new behavior.

This PR makes the modem_pipe instances track if they have
data ready to receive, and invoke the RECEIVE_READY event
every time they are attached if the backend implementing
the pipe has notified that receive is ready.
This mechanism ensures that modules attaching to a pipe
get the async RECEIVE_READY event immediately after
attaching to a pipe if there is data ready, instead of
having to poll the pipe, or worse, wait until newer data
becomes available.
The addition revealed a timing issue in the cmux test
suite. Specifically the CMUX instance now immediately
receives the response to a command which the CMUX
instance has not sent yet, causing it to drop the
response.
The CMUX test suite now uses the transaction
mechanism of the mock_pipe to wait for the command
before sending the response.

Convert pointer to string literal to array of char so that sizeof()
can correctly calculate size. Currently sizeof(msg) is effectively
sizeof(char *).

The tests test each module independently using the mock pipe,
which implements the modem_pipe API, making it compatible
with the modem modules.
The modem_ppp module is slightly different from the others
since it also interacts with the network stack. To acheive
this, a mock implementation of the PPP L2 net iface has
been implemented in the test suite for the modem_ppp.
