InputText, Nav: fixed tabbing through InputTextMultiline(). (#4761, #3092) 

Messy... Broken by 66f0fb9. Added ImGuiItemFlags_NoTabStop to EndGroup() ahead of time (not strictly needed here).

// If the current ActiveId was declared within the boundary of our group, we copy it to LastItemId so IsItemActive(), IsItemDeactivated() etc. will be functional on the entire group.
// It would be be neater if we replaced window.DC.LastItemId by e.g. 'bool LastItemIsActive', but would put a little more burden on individual widgets.
