bug(priproc) make last_day type a bit more accurate

Browse Source 
This fixes discrepance with the server, which assigns DATE type to
last_day()'s result.

Now we also assigns DATE result type and, also, use proper
dataconvert::Day data structure to return date.

Tests agree with InnoDB.

Also, this patch includes test for MCOL-5669, to show we fixed it.
