Add support for arm-based MacOS

[neopointer]

List of demos, from which:

• checked ones are working on my machine
• unchecked ones have not been tried out yet
• unchecked with error I'll leave some info

My specs:

• Macbook M1 Pro 2021
• openjdk 23.0.2 2025-01-21
• Edit: using version 3.4.0-SNAPSHOT of lwjgl, then more things work

All demos have been executed with the below command:

java -Dorg.lwjgl.util.Debug=true \
-Dorg.lwjgl.util.DebugLoader=true \
-XstartOnFirstThread \
-cp target/lwjgl3-demos.jar <class name>

• org.lwjgl.demo.bgfx

  • org.lwjgl.demo.bgfx.Bump
  • org.lwjgl.demo.bgfx.Cubes
  • org.lwjgl.demo.bgfx.Metaballs
  • org.lwjgl.demo.bgfx.Raymarch

For all above demos: no window is shown, but it somehow runs

• org.lwjgl.demo.cuda

  • org.lwjgl.demo.cuda.OpenGLExample
  • org.lwjgl.demo.cuda.SequencePTX

If I understood correct, CUDA does not work in MacOS at all

• org.lwjgl.demo.game

  • org.lwjgl.demo.game.VoxelGameGL

It runs, but there's an exception and I only see a white-ish screen:
