Description Of Change

This PR migrates queries related to getting the database version to TypeScript, as well as a few simple ones that only required moving to the code to the typescript file.

The real goal of the file is to implement a way to have internal code in query interface that cannot be accessed from the public API, but can still be modified by dialects.

This was done using AbstractQueryInterfaceInternal, see its uses in AbstractQueryInterfaceTypeScript and PostgresQueryInterfaceTypeScript. In the current implementation, Postgres does not replace the class with its own implementation, but it can when it starts needing to do that.

I also moved the logic for processing version queries out of query.js and into the query interface, with the long term goal of removing the query types used to format what are simple selects (VERSION, SHOWCONSTRAINTS, FOREIGNKEYS, DESCRIBE, SHOWINDEXES, SHOWTABLES)

Breaking Changes

• QueryTypes.VERSION has been removed
• AbstractQueryInterface#databaseVersion has been renamed to AbstractQueryInterface#fetchDatabaseVersion
