* Fixed static analysis warning
#jira UE-132273
* Fixed FSceneViewInitOptions::ShowOnlyPrimitives (a TOptional) being assigned a value - if no "show only" primitives are provided, we must pass an unset TOptional - otherwise an empty set will mean no primitive should be visible.
** Solves an issue with FMaterialUtilities::ExportLandscapeMaterial() being called by the USDExporter & World Composition LOD level generation

- works for starta and legacy conversion material
- legacy converted to strata setup the strata blending mode
- strata material also affect legacy blending mode because it is used in multiple places in the engine.
- works for lit and unlit legacy material
- to be fixed:
- lit with premultiplied alpha
- materials with multiple shading models

WP HLOD - Add Landscape support
Changes to support WP landscape material capture
* Moved IsValidBaseMaterial() from MeshMergeUtilities to MaterialUtilities
* Moved CreateProxyMaterialInstance() from MeshMergeUtilities to MaterialUtilities
* Added FCreateTexture2DParameters::bVirtualTexture
* Added FMaterialUtilities::ExportLandscapeMaterial() which doesn't need a list of primitives to hide (will only render the landscape component primitives)
* Added VT primming to ensure the captured textures have the expected resolution

Remove skinning pre/post offset functionality.
This were added in 4.26 specifically and temporarily for the MLDeformer prototype. (The public functions have always been marked as deprecated.)
MLDeformer now uses an Optimus deformer.

Supports either:
* From texel density
* From expected mesh screen size
* From expected mesh draw distance
Compute best texture size, taking UV map waste into account.
Currently only supported by the Approximate Actors merge method, to be integrated in the ProxyLOD later.

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.

* Added GroupIdenticalMeshesForBaking, which, when activated, will result in identical meshes (or mesh instances) being baked only once.
Other changes/fixes
* Always rely on the StaticMesh RenderData when retrieving mesh description for mesh merging/simplification (was the case when retrieving from a SMC, now also the case for a SM).
* For some reason, Material baking was rendering each triangle twice, but with opposite facing. Uneeded as we are rendering with backface culling disabled.

GetCurrentShaderPermutationFlags was being called which will always return the editor only data flag regardless of what platform we are cooking for which is the wrong behavior. I've changed this call to be GetShaderPermutationFlags which will check the layout parameters's flag for editor only data which will have per-platform information.
- Pass in TargetPlatform so we don't create the MaterialID as the current platform (in this case the cooker) which would be wrong.
- Pass LayoutParams to GetDependentShaderAndVFTypes so it can pass the appropriate editor only data flag into ShouldCompilePermutation.
