USD IO: register plugins in USD_create_handle().

Added call to ensure that the USD plugins are registered
when opening a USD cache archive.  This is to avoid USD
load errors due to missing USD file format plugins when
opening blender files that contain USD transform cache
constraints and mesh sequence modifilers.
