Fix mesh instance materials not initialized correctly

Browse Source 
This fixes a regression from PR #40313 (support for software skinning in MeshInstance).

Before, the base mesh was always updated on load even if not skinning
was used, which caused mesh instance materials to be reset on the
rendering side.

Now the base mesh is set only when it has been modified, or when
switching software skinning on or off. In this case the mesh instance
materials are always updated properly afterwards.
