Optional Windows Real COM Test (com0com)

SerialPortTest includes an optional section named windows com0com open/config/readback.

• Set SC_TEST_COM0COM_PORT_A and SC_TEST_COM0COM_PORT_B to enable it.
• Accepted values are both COMx and \\.\COMx.
• If both variables are unset, the section prints a skip message and succeeds.
• If only one variable is set (or values are malformed), the section fails with a configuration error.

Example command: SC.bat build run SCTest Debug vs2022 -- --test "SerialPortTest" --test-section "windows com0com open/config/readback"
