Nav, TreeNode: Pressing Left with ImGuiTreeNodeFlags_NavLeftJumpsBackHere now goes through proper navigation logic: honor scrolling and selection. (#1079, #1131)

Added a stack for this purpose which other features might build on (e.g. #2920). However this is currently gated by many tests and not a performance concern, but making stack happen all the time may be undesirable.
