  [mlir][bufferization] Implement BufferDeallocationopInterface for scf.forall.in_parallel (#66351)

The scf.forall.in_parallel terminator operation has a nested graph region with the NoTerminator trait. Such regions are not supported by the default implementations. Therefore, this commit adds a specialized implementation for
this operation which only covers the case where the nested region is empty.
This is because after bufferization, ops like tensor.parallel_insert_slice were already converted to memref operations residing int the scf.forall only and the nested region of scf.forall.in_parallel ends up empty.
