#fix Added new override point OnResetSkeleton, which allows UAnimSequence to wait for any in-flight compression tasks to finish before swapping out the skeleton

* Added overloads for FindSpecializedConversionNode and SearchForAutocastFunction that don't use output parameters. There are several instances in the engine where dummy variables are used to get around this.
* Updated the Message_ functions to use template parameter packing. The arguments are forwarded to the underlying FCompilerResultsLog, if one exists. This allows us to use tokenized messages.
* Changed several functions in FCompilerResultsLog to use the coding standard's naming convention. Specifically, arguments need to start with an uppercase letter.

This ensures that 'old' sparse class data (that may be regenerated by a compilation) is always stashed when beginning a compilation pass. This is needed because when sparse class data is cleared, all (loaded) child classes are also cleared, so when they also come to be compiled, their sparse class data will already be null and there will be a dangling reference to it in the package's export table (despite it being moved into the transient package). The dangling reference will then cause any subsequent loads (e.g. further children) to reference an invalid structure.

Due to reconstruction on edit, the member reference GUID was always conforming back to the original layer node once it was set. This fix ensures that the GUID is appropriately set each time the member reference is updated.

The source of the issue was that the key of the mapping between the original and the folded property was not able to distinguish between the instance of the node. This means that e.g. when we had several blend nodes in the graph, only one of the properties was in the map and thus all pin watches were watching the single folded property that the map contains.
This is now solved by using a graph pin as key for the map, which is unique per node instance.
An additional issue was that nodes like get variable were not compiled by the blueprint compiler and thus their pins were not part of the map as well. This got fixed by adding linked pins to the map as well.
The fix got verified in game as well. Please make sure to reload/recompile the "avg_player" and "sourcepose" anim bp before verifying.

Skeleton compatibility is now bi-directional. Specifying a compatible skeleton A -> B now implies B -> A.
Skeleton compatibility is now an editor-only concern. The runtime will attempt to do the 'best it can' via name -> name mappings. Only the editor will prevent assigning incompatible skeletons in (e.g.) asset pickers etc.
Skeleton compatibility checks in editor can now be disabled in the editor preferences (and each asset picker now has a checkbox option in its view settings that allows for quick access to this).
Moves FSkeletonRemapping to its own file (which is now private).
Skeleton remappings are now generated on demand on worker threads just before animation decompression and stored in a registry, guarded by FRWScopeLock for thread-safety.
Fixed some anim BP compiler edge cases where asset references on pins were not getting preloaded correctly, causing skeletons to be erroneously reported as missing.
Exposed the current asset registry filter in SAssetView so that menu extensions can access it (and use it to provide context)

[UE-168360] User can create a transition from a state into the entry state
* Relinking multiple transitions (transition nodes at once) when none of the transition nodes is selected.
* Selective relinking in case a subset of the transition nodes on a transitions are selected.
* Special case handling for transitions from entry state (they don't have a transition node connected).
* Drawing circle indicator around the arrow head in case the mouse cursor is approaching the transition.
* Hovering the arrow head of a transition highlights it by filling the circle with solid orange color and turning the arrow black.
* Ending the relink operation in empty space or the entry node will cancel the relink operation.
* Fixed bug that prevents creating new transitions ending in an entry state.
