build: Update ImGui and its dependencies (#1122)
This PR updates imgui and its dependencies from the last time, ~1 year
ago
(deabacbd50)

Commits will be refactored before merging

Things you might ask :
- why did you remove `ImGui_ImplGlfw_SetBorderlessWindowMode()` ?
-> Where is it used ? The only usage of it I see is commented
(cb9a3b1f55/lib/external/imgui/source/imgui_impl_glfw.cpp (L757))
- why did you remove the implot anti aliasing flag ?
-> They.. seem to have removed it altogether ?
