Implement partial support for SQL_INT128 datatype which is used for
DECIMAL/NUMERIC columns with a precision > 18. This support is only
available when QT_SUPPORTS_INT128 is defined and for MSVC.
Binding values to columns which need SQL_INT128 is supported but
numbers given as QString will be converted to doubles even if
QSql::HighPrecision is set.
[ChangeLog][SQL][IBASE] Added support for SQL_INT128 datatype.
