Method GcCompactTransientWindowBuffers

plugins/Cardinal/src/DearImGui/imgui.cpp:3156–3166

Free up/compact internal window buffers, we can use this when a window becomes unused. Not freed: - ImGuiWindow, ImGuiWindowSettings, Name, StateStorage, ColumnsStorage (may hold useful data) This should have no noticeable visual effect. When the window reappear however, expect new allocation/buffer growth/copy cost.
