* GLFW AUTO_ICONIFY flag is now set to false per default.

Previously AUTO_ICONIFY was only disabled if the user requested a Fullscreen window from the start. After that it was not possible to change this behavior on the user side anymore, even when changing to a Fullscreen window.

The AUTO_ICONIFY causes problems on macOS. On macOS if the window is minimized because of AUTO_ICONIFY than the only way to restore it is to click on the icon in the dock. In other words when AUTO_ICONIFY is enabled alt/cmd-tabbing through windows does not work correctly. On windows it works even when AUTO_ICONIFY is enabled.

Additionally if a raylib window is in Fullscreen mode on another monitor the AUTO_ICONIFY behavior is a problem because the user might want to window to stay on the monitor even if it loses focus. (problem on all OS's)

AUTO_ICONIFY also restores the monitor hardware resolution if a fullscreen window loses focus.

* Update rcore_desktop_glfw.c
