Currently it is not 'safe' for external code/scripts to be able to 'poke' data that is ostensibly thread-safe. Restricting to only private data is one possible option to solve this.
Gated behind a config flag for now as most content does not obey these rules at the moment.
This change also covers a case with 'valid' UObject use on worker threads where those UObjects are returned from thread-safe functions (which can only be native given the BP-level checks). It is assumed that the native thread-safe fucntion returning a UObject 'knows' that the UObject should be safe to access (e.g. some sub-object like a linked anim instance).

Providing a new flatten material with the correct texture samplers.
Retrieve texture properties from the default textures in the material (linear vs srgb, compression, vt enabled, lod group...)
Previously generated material instances are unchanged.
All MergeActor engine tests pass successfully.

"Call function" anim node:
- Adds the ability to call functions at different points in the anim graph execution (and under different conditions, e.g. when a branch has started blending in). Only thread-safe functions are allowed to be called.
- Adds a thread-safe override point BlueprintThreadSafeUpdateAnimation, called on worker threads for the main instance and for linked instances when they are relevant in the graph (only one call per frame for linked layer instances).
Subsystems:
- Added new override points pre/post event graph(s) (moved override point for worker thread work to around the thread safe update function call).
Improves property access integration:
- Property access now shows (and allows the user to override) the call site of accesses. This is to allow users to see when their property access calls will be made, hopefully making its use less confusing for power users.
- Tweaked UX for property access nodes and dropdowns.
- Anim node pins now have property access bindings in-line on the pin.
Also adds the abilility for the anim graph to opt-in (via a config flag) to more stringent thread safety checks. Disabled by default for now as this requires content fixup.

- Interchange per project settings allow user to create pipeline stacks and to override the pipeline selector UI
- First draft of the generic pipeline selector UI dialog
- Pipeline settings are saved in the config ini files
- The importAssetData now contains the pipelines settings so we can reuse the same settings when we will do the re import

- The mirage specific code is disabled behind the define UE_USE_VIRTUALBULKDATA, this means that some code paths in Texture/Mesh are much more complex than they need to be as we support both old and new paths. Once the system has been turned on and confirmed to cause no issues then this will be stripped out.
- SavePackageUtilities.cpp, SavePackage.cpp and SavePackage2.cpp are editgrates rather than integrations as those files have changes in DevCooker that we don't want to bring over immediately.
- Also includes a prototype system for storing bulkdata in a sidecar file in the workspace domain rather than in the .uasset/.umap file which although has been discontinued as part of mirage, will have applications for future work for non-virtualized projects and/or text based assets.

This change adds:
* Extraction of performance measurements from utrace to csv care of a SummarizeTraceCommandlet
* Filtering of those measurements into another csv file that is legible by the Horde telemetry system
* Split of iteration profile into two passes with differing DDC settings: cold with empty cache and warm with seeded cache
* Synchronization of async processing of assets to wait for processing to complete (as a user will do usually)
* Culling of unused pathways in IterationProfile.xml for brevity's sake

Per-node constant data is now held on a generated struct as part of sparse class data.
Per-node mutable data (i.e. pin links/property access mappings) is now held on a generated 'mutable data' struct that is compiled as part of the generated class.
The anim BP compiler is now extended more conventionally using UAnimBlueprintExtension, derived from UBlueprintExtension. This directly replaces the older 'compiler handler' pattern that was added in an emergency fashion for 4.26. Anim graph nodes now request their required extensions and these are held on the UAnimBlueprint in the UBlueprint::Extensions array. The Extensions array is potentially refreshed with any node addition or removal. The Extensions array is force-refreshed each time an anim BP is compiled for the first time to deal with newly added or removed requirements.
Const-corrected a bunch of UAnimInstance/FAnimInstanceProxy APIs that rely on (now truly) const data.
Added a split state/constant version of FInputScaleBiasClamp to allow some of its data to be split into constants.
Tweaked alignment/ordering of FPoseLinkBase to save a few bytes per pose link.
Deprecated FAnimNode_Base::OverrideAsset in favor of a more UAnimGraphNode_Base-based approach. Individual nodes can still have runtime overrides via specific accessors. The new approach will also give us the oppurtunity to override multiple assets per node if required in the future.
Moved property access into Engine module & removed event support from it - this was never used.
Reworked property access compilation API a little - construction/lifetime was a bit confusing previously.
Optimized path used to create UK2Node_StructMemberSet nodes in per-node custom events. When using mutable data, the structure used is large and very sparsely connected (i.e. only a few properties are written) so we only create pins that are actually going to be used, rather than creating all of them and conly connecting a few.
Patched the following nodes to use the new data approach:
- Asset players (sequences, blendspaces, aim offsets)
- Blend lists
- Ref poses
- Roots
