Function stb_textedit_replace

src/external/imgui/imgui_widgets.cpp:3830–3844

stb_textedit internally allows for a single undo record to do addition and deletion, but somehow, calling the stb_textedit_paste() function creates two separate records, so we perform it manually. (FIXME: Report to nothings/stb?)
