OSX: Disabled default native Mac clipboard copy/paste implementation in core library (added in 1.71), because it needs application to be linked with '-framework ApplicationServices'. It can be explicitly enabled back by using '#define IMGUI_ENABLE_OSX_DEFAULT_CLIPBOARD_FUNCTIONS' in imconfig.h. Re-added equivalent using NSPasteboard api in the imgui_impl_osx.mm experimental back-end. (#2546)

// CHANGELOG
// (minor and older changes stripped away, please see git history for details)
// 2019-07-21: Readded clipboard handlers as they are not enabled by default in core imgui.cpp (reverted 2019-05-18 change).
// 2019-05-28: Inputs: Added mouse cursor shape and visibility support.
// 2019-05-18: Misc: Removed clipboard handlers as they are now supported by core imgui.cpp.
// 2019-05-11: Inputs: Don't filter character values before calling AddInputCharacter() apart from 0xF700..0xFFFF range.
