Implement transmit idle notification for TTY backend. Since TTY
has an "infinite" transmit buffer, we invoke transmit idle
immediately after writing the data to the TTY file.
The test suite for the TTY backend has been updated to match the
new behavior.

Add fixture to test suite to allow for and signal that the test
must be run on real hardware.

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 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.

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.
