Add SetScreenSize to IConsoleDriver and fix test issues

- Added SetScreenSize(int, int) method to IConsoleDriver interface
- Implemented in ConsoleDriver base class to throw NotImplementedException
- Implemented in ConsoleDriverFacade to throw NotImplementedException
- Overridden in FakeDriver to call SetBufferSize for testing
- Updated all test files to use Application.Driver.SetScreenSize() instead of casting to FakeDriver
- Fixed FakeDriver_MockKeyPresses_Stack_Works test by clearing stack before use
- All tests now pass without casting (21 UnitTests + 16 Parallelizable FakeDriver tests)
