The original implementation created/destroyed framebuffers (FBs) per-frame, leading to kernel overhead and screen tearing. This commit replaces it with a different approach using:
- Asynchronous `drmModePageFlip()` with vblank sync
- Framebuffer caching to reduce repeated FB creation/removal operations
- Proper resource management through BO callbacks and buffer release synchronization
- Added error handling for busy displays, cache overflows, and flip failures
- Event-driven cleanup via page_flip_handler to prevent GPU/scanout conflicts

I believe it makes sense to only do this when there are no known
touch points. I am not even sure if this should be done at all.
See https://github.com/raysan5/raylib/issues/4872 for more information.
Restore window currently says it sets the window state to:
"not minimized/maximized"
However, if a window is maximized and then minimized, it's typical that
it would restore back to being maximized, which is what seems to happen
from my testing. I've reworded the description to better reflect
this behavior.
raylib app crashing when started and a gamepad is already connected to the PC (even if the gamepad is not used in the app). I only tested this with a gamepad that has a layout which is not recognized. Using SDL3 as backend.
This may not be the correct approach, however this appears to work. The idea is that before modifying `CORE.Window.flags` when first creating the window we keep a copy of the flags in order to call `SetWindowState` after initialization has completed, which should behave as if `MaximizeWindow` or `MinimizeWindow`, or conceptually any other flag modifying function were called after `InitWindow`.
This pull request only performs this for the windows platform, modify as needed in the switch statement at the end for others.
Raylib allows for providing custom allocators via macros.
GLFW supports this too, but via function pointers.
Make sure that GLFW uses those Raylib macros, by wrapping them in
function calls and setting them up inside of InitPlatform().
This is possible because of glfwInitAllocator() and GLFWallocator.
