Normally we would aim to ensure that g.Windows[] gets maintained to reflect display layer but it is presently non trivial.

Docking+Viewports Branch:
- Docking: Revert removal of io.ConfigDockingWithShift config option (removed in 1.83). (#4643)
- Backends: Made it possible to shutdown default Platform Backends before the Renderer backends. (#4656)

Docking+Viewports Branch:
- Docking: Revert removal of io.ConfigDockingWithShift config option (removed in 1.83). (#4643)
- Viewports: Made it possible to explicitly assign ImGuiWindowClass::ParentViewportId to 0 in order
to ensure a window is not parented. Previously this would use the global default (which might be 0,
but not always as it would depend on io.ConfigViewportsNoDefaultParent). (#3152, #2871)
- Viewports: Fixed tooltip in own viewport over modal from being incorrectly dimmed. (#4729)
- Backends: Made it possible to shutdown default Platform Backends before the Renderer backends. (#4656)
- Disabled: Fixed nested BeginDisabled()/EndDisabled() bug in Docking branch due to bad merge. (#4655, #4452, #4453, #4462)
