Add query for terminal size

[zoziha]

Motivation

Fortran is often used to develop console backend programs. In certain scenarios, there may be a need to obtain the terminal size to display content appropriately.

Similar to Python, this routine is suitable to be placed in stdlib_system (OS, Operating System).

Prior Art

• C/C++:
  • Unix/Linux: Obtain the winsize structure through the ioctl system call and the TIOCGWINSZ command;
  • Windows: Use the GetConsoleScreenBufferInfo API to obtain console buffer information.
• os.get_terminal_size in Python.
