Windows: store BgClickFlags which allows the equivalent of io.ConfigWindowsMoveFromTitleBarOnly to be overridden on a per window basis. (#899, #3071, #5044, + #3379)

Browse source 
io.ConfigWindowsMoveFromTitleBarOnly now sets initial value for BgClickFlags. Using e.g. ImGui::GetCurrentWindow()->BgClickFlags &= ~ImGuiWindowBgClickFlags_Move; allow per-window override.
This will be extended for supporting scrolling options for #3379.
As a minor side effect: the effect of enabling io.ConfigWindowsMoveFromTitleBarOnly now happens one frame later ('window_modal_bounds_exceeding_work_area" test accidentally broke in some situations because of that)
