[Trafodion-2335] support functions in the column default definition
This PR add the support in column default definition the expansion to use
following functions:
uuid
unix_timestamp
to_char
To support to_char, it saves the original text of full to_char function,
and save it as DEFAULT_VALUE in "_MD_".COLUMNS.
And the INSERT binder will get this original string, and parse into the
ItemExpr tree.
The semantic check is done in setDefaultAttribute.
UUID/UNIX_TIMESTAMP follow the current_timestamp implementation.
