   Support list type for gandiva expression inputs and outputs.
   - add `list<utf8>`, `list<int>`, `list<float>` type for expression inputs 
and outputs
   - add two function for `list<utf8>` inputs: `array_length(list<utf8>)`, 
`array_contains(list<utf8>, utf8)`
   
   TODO:
   - current structure can support list<decimal> type, but should handle extra 
precision and scale
   - as for `list<bool>` type, should add extra function to get bits list for 
computations
