ImguiAtomSystemComponent isn't guaranteed to initialize before ImGuiManager, which caused some issues.
Additionally, because we allow the user to configure ImGui's render resolution, I've refactored the window size override into a new OverrideRenderWindowSize API in ImGuiManager to decouple it from the target render resolution.
