* Unifies the different places creating a Layer Info Object or accessing "sharedassets".
* Fixes UEFN not able to access created LayerInfo objects in the ContentBrowser
* Adds the ability to create Landscape Layer Info Object as a regular asset (ie: without the landscape editor). Needed for example to create a Default LandscapeLayerInfoObject

Also restores follow-up CLs 19973746, 19973782
FStaticParameterSet::MaterialLayers can't be deprecated, since a property with the same name is included via FStaticParameterSetRuntimeData
So instead, FMaterialLayersFunctionsRuntimeData is updated with SerializeFromMismatchedTag, to allow serializing a full FMaterialLayersFunction.
When this happens, the EditorOnly portion is stored in a separate heap allocation, and then transferred to FStaticParameterSet::EditorOnly::MaterialLayers

Add 'Optional' EditorOnly data for UMaterialInterface and UMaterialFunctionInterface
These are separate UObject hierarchies that store editor-only UPROPERTIES, but can be included with cooked content, which allows full editor support.
In principle, all editor-only properties could be moved over. So far, this has been limited to UMaterialExpressions, and data related to material parameters.
FStaticParameterSet, FMaterialLayersParameters, and FMaterialCachedExpressionData have all been split into separate editor-only/non-editor-only classes,
which allows the editor-only portion to be stored on the optional editor-only UObject.

Original CL Desc
* Removed incomplete per-platform per-LOD level material overrides for landscape. The code isn't meant to support that since material instances are built at edit-time. We would need to somewhat hack it at cook time in order to regenerate (and recompile) the list of material instances per-platform, which is not a recommended thing to to in the engine. Instead, we choose to simply make the per-LOD level material overrides constant across platforms since the recommended way is to customize the material for platforms using material expressions such as Quality Level switc, Shading Path Switc or Feature Level Switc.
* Deprecated/merged FLandscapeComponentMaterialOverride and FLandscapeProxyMaterialOverride into FLandscapePerLODMaterialOverride since they were identical
* Fixed UpdateLayersMaterialInstances which, unlike UpdateMaterialInstances, didn't take into account per-component material overrides

Cooking a ULandscapeComponent is updating a LandscapeMaterialInstanceConstant and the landscape MIC has already had BeginCacheForCookedPlatformData() called on it.
Here is what's happening:
UMaterialInstance::BeginCacheForCookedPlatformData is called for a Landscape MIC
This MIC's bHasStaticPermutationResource == false so no resources are cooked for the MIC. The MIC's CachedMaterialResourcesForCooking is empty.
ULandscapeComponent::BeginCacheForCookedPlatformData is called on a Landscape component.
The Landscape component changes the MIC to have a static permutation and calls `CombinationMaterialInstance->UpdateStaticPermutation(StaticParameters, InMaterialUpdateContext);`
We then go to Save the MIC, which now has bHasStaticPermutationResource==true, but it doesn't have resources cached for cooking and triggers the assert.
The new code ensures we call `BeginCacheForCookedPlatformData` on any material instances created during landscape generation while cooking.

WorldPartition - Added Lanscape HLODs
Created a custom HLOD builder for ULandscapeComponent
* Landscape LOD used to generate the HLOD is autocomputed from the expected draw distance, same for the baked texture size
* Expose ALandscapeProxy::GetLODScreenSizeArray()
* Actually reverting changes done in CL 18794652 (moving proxy mesh creation back to ALandscapeProxy)
* ComputeLayerHash() now takes a bool to choose if we want to compute the hash for edition or runtime data
