Added missing Windows functions for console manipulation

This commit adds several missing types and functions to the Windows implementation to enable manipulation of console windows. The types added include 'SMALL_RECT', 'CONSOLE_SCREEN_BUFFER_INFO', and 'PCONSOLE_SCREEN_BUFFER_INFO'. The functions added include 'GetConsoleScreenBufferInfo', 'SetConsoleScreenBufferSize', and 'SetConsoleWindowInfo'. These functions were necessary to properly manage the console window.
