Window adjustments and fixes for all backends

[AloXado320]

Main changes for all backends

• Adjust window position and size if a game requests a larger resolution than the current resolution.
• When window size it's changed, it now gets centered if is not maximized and caches the size so it doesn't prevent resize.
• WIN32 time commands are now set in GLFW backends, no need to set on SDL backends since they already do internally.

Specific backend changes

GLFW2

• Fixed cursor being locked on Windows when it's invisible.
• Fixed sleep to prevent negative values (Viral Nightmare was affected by it, not other games for some reason).

SDL1

• Added alternative way to get max resolution on very old versions (GCC 2.95/3.0 requires it).
• Made it so Alt+F4 actually closes the window.

SDL3

• Ported over HIDPI changes from SDL2.
• Adjusted window Y position so on larger resolutions, the title bar is still visible.

Description

• Fixes MMX Viral Nightmare, Shotgun Witch and probably other games from setting a larger resolution.
• Fixes Orbinaut Framework games (eg: Sonic Revisited) setting a large then a small resolution, hiding the title bar.
• Fixes CD-I Remasters from setting the windows size every frame, making them unresizable.
