make TIMESTAMP use whole 32-bit unsigned range

Details

    Description

      Currently timestamp is 32-bit signed, although negative values are rejected, so it is de facto 31-bit, allowing values from 1970 to 2038.

      We can make it 32-bit unsigned extending timestamp range to 2106, and it won't require many changes to the storage.

      Storage of timestamp is not affected but the change.
      However storage of 'row_end' for system versioned tables must change from storing a 2038 based timestamp to a 2106 based one.
