Mesh bounds not calculated on runtime import

[andypoly]

Describe the bug
Mesh bounds not calculated on runtime import because MeshGenerator class calls GenerateMesh(),CreateMeshResultAsync which checks for "boundsAreValid". If they are then it never calls msh.RecalculateBounds() which means post-load the mesh does not have any relevant bounds (they are centre 0, size 0).

To Reproduce
View and debug the code as above for probably any glb (but can provide validated glb if required) - the mesh will end up with no bounds - only the submesh has bounds calculated

Expected behavior
Any generated meshes should have RecalculateBounds() called on them.
See https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Mesh.SetSubMesh.html
It says "Note that this only applies to the bounds of the SubMesh. You must call Mesh.RecalculateBounds to recalculate the bounds of the Mesh itself."
