Add ALTER FULLTEXT INDEX statement parsing
- Add SimpleAlterFullTextIndexAction for ENABLE/DISABLE/POPULATION actions - Add AddAlterFullTextIndexAction for ADD (columns) action - Add DropAlterFullTextIndexAction for DROP (columns) action - Add FullTextIndexColumn type with TYPE COLUMN and LANGUAGE support - Handle SET CHANGE_TRACKING with MANUAL/AUTO/OFF options - Support WITH NO POPULATION clause Enable AlterFulltextIndexStatementTests and SetCommandsAndMiscTests tests. Mark PhaseOne_AlterFulltextIndexTest as todo due to type name mismatch.
