Fix | Build DataTypes table in code, add json data type (#3858)

* Create structure of DataTypes static population
* Remove redundant data types from metadata
SqlClient cannot connect to SQL Server 2000 instances, so the minimum server version is 9.0.
* Remove data type entries with a maximum version below this.
* Remove the minimum version constraint where this constraint will always be true.
* Populate DataTypes table from MetaType information
* Add test to verify presence of data types
* Add json data type to DataTypes schema collection
* Use IsJsonSupported more widely
This enables the JSON tests to run against SQL Server 2025.
Also correct a comment in LoadDataTypesDataTables.
* Plumb minimum version logic to AddStringOrBinaryType
* Address MARS JSON test failure
This was manually constructing a connection string, which didn't work on one CI leg.
