Mcol 5092 MODA uses wrong column width for some types (#2450)

Browse Source 
* MCOL-5092 Ensure column width is correct for datatype
                       Change MODA return type to STRING
                       Modify MODA to handle every numeric type
* MCOL-5162 MODA to support char and varchar with collation support

Fixes to the aggregate bit functions
When we fixed the storage sign issue for MCOL-5092, it uncovered a problem in the bit aggregates (bit_and, bit_or and bit_xor). These aggregates should always return UBIGINT, but they relied on the type of the argument column, which gave bad results.
