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.

remove this break; it does nothing

This is a very big diff, and it has parts that I know aren't ready. Could you make a 2nd PR with just the following bits that are pretty simple and look ready

SDL1 ALT+F4 fix
SOME of the SDL3 HIDPI changes, have the new platformGet(Scaled)WindowSize, and remove fbWidth/fbHeight and all that, but don't create a HIDPI window
time(Begin/End)Period changes
GLFW2 platformSleepUntil cast fix thing
All the other small stuff, like tweaks to comments and layout changes that make the code nicer with no functional difference.

There were window related fixes as the title said, though it makes sense to add some of them separately, the small fixes would be a separate PR, though for the window things it would make more sense to actually implement the window VM builtins (fullscreen, window pos, center, etc).

Would keep it as a draft and take it's changes separately so it can be properly reviewed, the idea would be like this for each PR:

• Backend fixes only (glfw2 sleep/mouse, glfw time functions, sdl1 alt+f4)
• SDL3 HIDPI
• Window VM implementation for each backend

The large resoultion fix could be in the window vm pr or after it was reviewed or merged (alongside support for old sdl1.2/sdl2.0).
