rcore_desktop_glfw.c : fix HDPI scaling on Win11 + window restoration on Wayland

Browse Source 
As a general rule, Raylib API functions should not be used internally by the platform code, because these functions may be tuned for cross-platform consistency so they return consistent data relevant to the user perspective, and not to the platform code perspective.

I don't know if it is a GLFW bug, but on Wayland, the `WindowSizeCallback()` is not called when the window is restored from a fullscreen mode, and I had to workaround that.
As discovered by @SoloByte, using `glfwSetFramebufferSizeCallback()` instead of `glfwSetWindowSizeCallback()` solves this issue on Wayland, and deprecate the workaround.
