Enhancement: Options Window Screen Adjust

[khuonghoanghuy]

What is your suggestion, and why should it be implemented?

May some screen would display the game too small or too big to let player see, so if you guy can, please added window screen options adjust like (1280x720, 1368x769,...)

Window size settings would be nice to have for people who prefer a setting over manually resizing the window. Plus, people would probably encounter https://github.com/FunkinCrew/Funkin/issues/2694 much less often.
