Re https://github.com/apache/arrow-datafusion/pull/786
Changes:
1. Reduce size of ScalarValue from 64 bytes to 32 bytes by boxing
`ScalarValue:List`s internal parts
# Rationale for this change
1. A smaller `ScalarValue` means switching to use it in hash aggregations
and hash joins will not be as expensive memory wise (where one is instantiated
for each distinct grouping value)
