Port FIRST_DAY function to Db2 for i

IBM Db2 11.1 introduced a new scalar function FIRST_DAY to return the first day of the month.

Please port this function to IBM Db2 for i.

Use Case:

Make SQL more readable.

Make SQL more portable between IBM Db2 for other products.

Potentially better performance from a native function vs. a UDF to compute this value.

The similar function LAST_DAY already exists in Db2 for i.
