Add views for periods in information_schema

Details

    Description

      System-versioned tables can be recognized in information_schema by TABLES.TABLE_TYPE being SYSTEM VERSIONED. Application-time period tables, however, are indistinguishable. They present in TABLES view as BASE TABLE, and the period looks like a regular check constraint both in CHECK_CONSTRAINTS and TABLE_CONSTRAINTS. As discussed earlier on Slack, the standard defines some period-specific views, I think at least most basic ones should be added.
