Viewports, Backend: SDL: Fix missing ImGuiBackendFlags_HasSetMousePos…

… flag in docking branch (ok in master), GLFW: Fix application of WantSetMousePos. (ocornut#1542, ocornut#787) Shows how little this feature is used with nav (was designed for small devices and frankly may be dropped) - but the backend support itself we will make use of for other features.
