IO: Added AddMousePosEvent(), AddMouseButtonEvent(), AddMouseWheelEvent() api + updated all Backends. (#4858) (input queue code will be next commit)

Browse Source 
Details: note that SDL, OSX and GLFW backends removed recording of MouseJustPressed[] which will be unnecessary with input queue (which is the NEXT commit). (#2787, #1992, #3383, #2525, #1320)
