   **Is your feature request related to a problem or challenge? Please describe what you are trying to do.**
   Like Decimal128Array, I think Decimal256Array should be also compared with a scalar.
   ```
   use arrow::array::{Decimal128Array, Decimal256Array};
   use arrow::compute::kernels::comparison::eq_dyn_scalar;
   use arrow::datatypes::i256;
   
   
   fn main() {
       let decimal128_array = Decimal128Array::from(vec![1_i128, 2_i128, 3_i128]);
       let decimal256_array = Decimal256Array::from(vec![i256::from_i128(1), i256::from_i128(2), i256::from_i128(3)]);
       println!("{:#?}", eq_dyn_scalar(&decimal128_array, 2_i64)); // Ok
       println!("{:#?}", eq_dyn_scalar(&decimal256_array, 2_i64)); // Error
   }
   ```
   output:
   ```
   Ok(
       BooleanArray
       [
         false,
         true,
         false,
       ],
   )
   Err(
       ComputeError(
           "Unsupported data type Decimal256(76, 10) for comparison eq_scalar with 2",
       ),
   )
   ```
   Should be:
   output:
   ```
   Ok(
       BooleanArray
       [
         false,
         true,
         false,
       ],
   )
   Ok(
       BooleanArray
       [
         false,
         true,
         false,
       ],
   )
   ```
