    [SPARK-12848][SQL] Change parsed decimal literal datatype from Double to Decimal

    The current parser turns a decimal literal, for example ```12.1```, into a Double. The problem with this approach is that we convert an exact literal into a non-exact ```Double```. The PR changes this behavior, a Decimal literal is now converted into an extact ```BigDecimal```.
    
    The behavior for scientific decimals, for example ```12.1e01```, is unchanged. This will be converted into a Double.
