GeometryScript: explicitly clear SectionInfoMap in CopyMeshToStaticMesh() instead of clearing entries one at a time, which is wrong if only some sections are in the map

This change addresses the errors found with applying certain modeling tools to skeletal meshes due to the old code not using the appropriately setup MeshDescription for skeletal meshes.

- Fixed snapping not disabling with Shift key.
- Fixed inability to end path if enabling snapping after starting the path.
- Fixed some undo items being undoable in certain circumstances.
- Fixed 0 height paths being treated differently than what PolyExt does (now they are unextruded ribbons instead of 0 thickness extrusions).
- Fixed interactive width selection not aligning with actual sides of path.
- Made behavior more intuitive when using fixed height/width/radius parameters and switching between fixed and interactive modes, including making it possible to set the fixed parameters after leaving that step of creation.
- Made radius setting behavior similar to width setting behavior.
- Disallowed 0 width paths.
- Made 0 radius same as not having rounded corners.
- Made the tool complete a current mesh if exited while one is ready.

Add new MeshTargetInterfaceTypes.h file, move EStaticMeshEditingLOD there and rename to EMeshLODIdentifier. Add FGetMeshParameters and FCommitMeshParameters types.
IMeshDescriptionProvider::GetMeshDescription() now takes FGetMeshParameters to optionally specify LOD.
Added IMeshDescriptionProvider::GetMeshDescriptionCopy() function, to handle copy-case.
removed IMeshDescriptionProvider::CalculateAutoGeneratedAttributes(). This was only being used to force Tangents computation, which can now be done via GetMeshDescriptionCopy() and FGetMeshParameters.bWantMeshTangents option
IMeshDescriptionCommitter commit functions now take a FCommitMeshParameters to optionally specify target LOD.
StaticMeshComponentToolTarget::GetMeshDescriptionCopy() added, optionally computes auto-generated MeshDescription attributes on the copy
StaticMesh(Component)ToolTarget updated to support FCommitMeshParameters target-LOD.
SkeletalMesh, Volume, and DynamicMesh ToolTargets updated for new APIs but do not currently support any of the new LOD parameters. These should never be called w/ LOD parameters in the current codebase, ensures added to catch any errors (they would be non-fatal).
UE::ToolTarget::GetMeshDescription() and GetMeshDescriptionCopy() in now take FGetMeshParameters argument.
Removed bWantMeshTangents param to GetMeshDescriptionCopy(), now done via FGetMeshParameters. Updated call sites.
TransferMeshesTool now supports specifying read and write LOD (numbered or HiRes) for StaticMeshComponent source/target, via above functions.
TransferMeshesTool can now also target a new LOD in a StaticMeshComponent, index is 1 larger than current maximum source LOD.

Reduce surface area of MeshDescriptionProvider/Committer, replace with UE::ToolTarget:: calls where possible.
Add new UE::ToolTarget::CommitMeshDescriptionUpdateViaDynamicMesh() function. This is being used for now to avoid potential regressions as UE::ToolTarget::CommitDynamicMeshUpdate will preferentially use DynamicMeshCommitter, and I am not certain it is functionally equivalent in all cases.
Add new UE::ToolTarget::CommitDynamicMeshNormalsUpdate(), similar to existing UV version
Add new Move-variant of UE::ToolTarget::CommitMeshDescriptionUpdate(), uses new Move-variant of IMeshDescriptionCommitter::CommitMeshDescription.
Make existing IMeshDescriptionCommitter::CommitMeshDescription callback interface protected, to prevent usage of this function at public API level (will be removed in future).
Tool updates should not change, just using cleaner APIs.
EditNormalsTool now uses CommitDynamicMeshNormalsUpdate(), which does go via DynamicMeshCommitter preferentially, where it previously went via MeshDescriptionCommitter. In light testing the results appear equivalent.
AttributeEditorTool now operates on MeshDescription copies in various update functions. These are not performance-critical.
