[Format] Tensor.fbs file has multiple root_type declarations

[asfimport]

Looking at the flatbuffers doc, it appears there should only be one root_type declaration in an fbs file:

The last part of the schema is the root_type. The root type declares what will be the root table for the serialized data. In our case, the root type is our Monster table.

However, the Tensor.fbs file has multiple root_type declarations:

arrow/format/Tensor.fbs

Line 53 in 69d595a

root_type Tensor;

arrow/format/Tensor.fbs

Line 146 in 69d595a

root_type SparseTensor;
