[contrib.glfw3] new version 3.4.0.20241004 (emscripten-core#22695)

I released a new version 3.4.0.20241004 with the following release
notes:

- Implemented custom cursors (`glfwCreateCursor`)
- uses a canvas to draw the cursor image into it and convert it into a
URL (`canvas.toDataURL()`)
- uses the CSS property syntax: `cursor: url(xxx) xhot yhot, auto` when
calling `glfwSetCursor` with a custom cursor
