Subject: [PATCH] [Planner] Align Date and Datetime by 16 bytes (#6105)

The previous alignment of Doris is up to 8 bytes.
For types with more than 8 bytes, such as Date, Datetime is not aligned.
This PR is mainly to relax the maximum 8-byte limitation
Also, because the data type Decimal v1 no longer exists,
the logic of the 40-byte Decimal v1 is also discarded.
