…nd spmd partitioner. Explicit batch dimensions and index parallel dimensions cannot co-exist. Namely, if a gather/scatter has explicit batch dimensions, we do not consider index parallel dimensions in it. The default and prioritized method to partition gather/scatter is now processing explicit batch dims, while it was index parallel dims before this cl. PiperOrigin-RevId: 697033844
