The modem pipe APIs include synchronous calls to open/close,
which internally use a fixed timeout of 10 seconds. The timeout
should be configurable through the APIs, anywhere from K_NO_WAIT
to K_FOREVER.
This commit adds timeout parameters to the open/close APIs, and
updates in-tree usage of the open/close APIs to explicitly
provide the previously implicit timeout of 10 seconds.

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.
