Sync columns in contact_details table, add missing defaults, clean up

[csthomas]

Pull Request for issue #13289
To help #7680 on mssql

Summary of Changes

1. Add missing defaults for columns [all db]:

• xreference
• sortname1, sortname2, sortname3
• metakey, metadesc - column type TEXT can not have default value for mysql

2. Add missing default for sqlsrv only:

• checked_out
• created_by_alias
• published

3. Remove defaults because that columns can not have default '' for :

• name
• alias
• language # for postgresql only

4. Remove DEFAULT NULL or alone NULL from sql files because this is redundant.

5. Clean up for postgresql:
   Replace DEFAULT 0 NOT NULL to NOT NULL DEFAULT 0
