This change represents the final round of improvements to the Sequencer outliner UI per UX team's mockups. The notable changes are:
- All widgets on the outliner are now properly aligned and maintained through a rich and extensible column management API. All columns can be toggled on and off as desired.
- Previous/Add/Next key navigation buttons have updated icons and spacing and are consistent with the pin/lock/mute/solo icons
- Labels and edit widgets will now forcibly overflow other, less important, widgets on hover if they are occluded because of a narrow overal outliner width
- All rows now have a separator line
- Track rows are now uniform heights
- Lock camera button is now more prominent

The SequencerOutlinerScriptingObject now has GetNextKey/GetPreviousKey functions which can be called from scripts.
SequencerOutlinerViewModel implements GetNextKey/GetPreviousKey
GetNextKey/GetPreviousKey now operate within the the sequence's time bounds (which can be restricted to the selection range)

- TableRowStyle for Sequencer which is a combination of the alternative row style and the show parent style - Alternating rows have different tints, parents have different tints.
- Make sure top level rows also report as a parent row
- Rows that have keys or sections selected also report as highlighted

The Binding Lifetime track is an optional track that can be added to any object binding. It allows the user to set time range(s) for when the object in question will be bound by Sequencer. Outside of those ranges, the object will be released, and any tracks underneath it will restore state/keep state as set.
Currently this track works for both spawnables and possessables. This track is a precursor to other binding types coming to Sequencer, and in the future this track will allow the user to trigger events as part of the binding activation/deactivation so that changes like AI control for example can be set when binding/unbinding NPC characters or player characters.
As part of this change, it was necessary to clean up some of the sequencer UI color settings on labels, as well as a few changes to the layer bar UI to facilitate a hatch overlay for the sections of the binding tracks that are in a deactivated area.

+ Added a new row type for outliner trees that sets the background color once for the whole row. Previously this logic was implemented by each widget within the row (now each column widget, and the outliner view widget), which meant we re-ran the exact same logic (that was copied around) for background color computation multiple times per row. We now only do this once for the whole row.
+ Added a ModelID to all MVVM models. This is just a non-persistent serial uint32 unique to the instance and can be used for more efficient and stable keys than using the instance ptr.
+ SharedData is now a view model so it can support arbitrary extension and casting. This enables us to:
+ Add a new hierarchical cache extension that is easily accessible from any widget using GetSharedData()->CastThis<FOutlinerCacheExtension>()
+ Hierarchical Cache will perform a single pass on the entire MVVM hierarchy and allow clients to compute cached flags.
+ We have a separate cache for each of mute, solo and lock states that includes whether the item is set directly, and also whether it has settable children, and is implicitly set by a parent or child.
+ Added a dynamic extension iterator that allows anyone to iterate and filter the currently active dynamic extensions.
+ Moved Mute and Solo logic into the actual mute / solo extensions, rather than it being implemented in the NodeTree
+ Fixed header coloration for collapsed outliner rows that had selected keys within them. The logic here was incorrect and looked like an error in porting the code. It is now correct (and more efficient).
- Only folders, objects, tracks and track rows now implement mute/solo. Channels and categories were never supported, and now no longer show as such on the UI.
- Deleted the pre-existing XYZEditorExtension classes since they have all been ported to these new caches (the code is largely the same)

As part of this, change display name tooltips on tracks back to using a function rather than a saved value so they can be dynamically specified. This needed Sequencer and ObjectBindingID passed to the function for context. This was only very recently changed to use saved values, so this shouldn't cause issues.
