Optimize Material Baking (Phase 1)
- Introduce a mecanism to override the vertex/index buffer allocator used for dynamic meshes
- Avoid GDynamicMesh non-ticked pools build-up by using our own vertex/index buffer pool during baking
- Reduce reallocation and incurred soft page faults by reusing a single set of vertex/index buffers big enough for the biggest mesh
- Preemptively detect if smearing would result in monochrome texture to avoid useless work
- Shrink smeared monochrome textures during the baking process for huge memory savings
- Move UV smearing in worker threads to avoid blocking the game thread
- Required shaders are now built asynchronously
- Add progress bar for material baking
- 28m23 [at] 150 GB RAM -> 2m14s [at] 45 GB RAM for 6 channels [at] 512x512 when baking materials on ProxyLOD for DATASET-0008a with DDC empty

Optimize Material Baking (Phase 2)
- Implement pipelining with staging buffers to avoid GPU stalls when reading from render targets
- Reuse the same prepared FMeshBatch instead of rebuilding it for each draw pass
- Prepare the RenderItem in advance on other threads to reduce work on the game thread
- Move the staging surface copy out of the render thread
- Small vertex and index buffers are not reused to avoid dependency locks when mapping them
- Fix bug in Canvas Flush_RenderThread found while running HLOD rebuild commandlet on Fortnite
- Delete old and unused MaterialBakingModule.h from public files
- 4m44s -> 59s for baking 6 channel [at] 1024x1024 when baking materials on ProxyLOD for DATASET-0008a with shaders already compiled
- Time spent in Material Baking when rebuilding all HLOD on Apollo_POI_Large_HLOD (Phase 1 + 2 combined)
- 10m18s -> 2m36s for a first rebuild all in editor with no shaders in DDC (cold)
- 1m23s -> 20s for a second rebuild all in editor (warm)

Optimized mesh merging
* Added DeletePolygons() & DeleteTriangles methods to FMeshDescription which rely on TSets<> instead of performing costly TArray::AddUnique() calls()
* Parallelized UV generation and avoided duplicate processing of the same mesh+lod pairs
* Optimized FMeshDescriptionOperations::GenerateUniqueUVsForStaticMesh()
* Goes from 100s to 10s in my test case
