Deprecation of FPlatformMath::IsNegative*() functions.
New FPlatformMath::IsNegativeOrNegativeZero().
Fix up of existing usage to either use < 0 or IsNegativeOrNegativeZero where appropriate.
Fixes for aliasing problems in various FMath functions, including IsNegative*().
Resubmission of CL# 19833778 with fixes for problematic Mac and Android toolchains, causing spurious errors while building PCHs.

The function would remap polygroups of the source meshes, then use FStaticMeshOperations::AppendMeshDescription() which would also mess with the groups.
Providing a polygroup delegate to AppendMeshDescription() solves the issue.

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

Changed fallback settings to be largely error based with new property FallbackRelativeError.
Nanite builder will now provide the LOD fallbacks for all autogenerated LOD levels which is far faster than generating them from scratch.

FLinearColor has also been modified to make any double->float conversions explicit. Previously all 3D TVector versions were allowed to be implicit and thus could convert TVector<double> => FLinearColor => TVector4<float>.
Fixed up all engine and game casts. Added "//LWC_TODO: precision loss" around any explicit casts that previously were silently explicit and we may need to revisit for precision loss analysis.

Primary goal is to reduce amount of code duplicated across different parameter types, and reduce amount of boilerplate required to add new parameters
The main part are new types FMaterialParameterValue, and FMaterialParameterMetadata (both in MaterialTypes.h). FMaterialParameterValue is a tagged union/variant type, that can represent any material parameter value. FMaterialParameterMetadata contains a value, along with various editor-only fields that describe how that value is used.
Using this new type, many places that previously included separate APIs for each parameter type collapse to a single API that operates on a FMaterialParameterValue/FMaterialParameterMetadata. Code that previously had a block copy/pasted for each parameter type can be replaced with a loop that iterates over all parameter types.
Also includes some API cleanup that should improve (editor) performance. Previously we had APIs GetAllScalarParameters, GetAllVectorParameters, etc, which would return a list of FMaterialParameterInfos for each parameter of the given type. Code would often query all parameters, then loop over the results and lookup each parameter value. Now there's a new API, GetAllParametersOfType, which returns a list of all FMaterialParameterMetadata of a given type. It's easy to just collect the values at the time we're building the list of parameters, so this saves the work of looking up each value individually.
