Added CMake support for SDL3.
Now supports including SDL2 or SDL3 as a subdirectory within the project. The system will first check for SDL3, then SDL2. If neither is found, it will attempt find_package(SDL3), followed by find_package(SDL2). If all these checks fail, the process will terminate with an error.

corrected coding conventions.

Bug Fix Update
Code to Ignore Hovering Inputs Completely

It is called on window minification and setting internal width/height to 0, that can break things

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.

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.

This change is replacing the hardcoded "#canvas" element references in
rcore_web to allow using canvas elements that use different names
(which is necessary when using multiple canvas elements on one page).

Also adding a cursor hiding example to mouse example.
