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)

// 2022-01-10: Inputs: calling new io.AddKeyEvent(), io.AddKeyModsEvent() + io.SetKeyEventNativeData() API (1.87+). Support for full ImGuiKey range.
// 2019-04-03: Misc: Renamed imgui_impl_freeglut.cpp/.h to imgui_impl_glut.cpp/.h.
// 2019-03-25: Misc: Made io.DeltaTime always above zero.
