[Feature] Add: "Scaffold Data API Builder configuration" to Server Explorer context menu

[ErikEJ]

This is stage 0.9, just to get something out!

1: Server Explorer can store connections to SQL Server/Azure SQL by default, and additional DDEX providers for Postgres and more are available. Connections to MS SQL and Postgres are supported

2: Show tables, views and SQL Server (not Postgres) stored procedures, including all columns

3: For this iteration, use this algorithm to determine a suggested key for a view, and indicate visually with a spcial icon. Add comment about the key choice in the output:

• Pick first column named Id
• Else pick first column ending in Id
• Else pick first column

4: Output:

• .cmd file with commands to install DAB CLI and run the required config commands with comments as needed
• explicitly specify each table with all columns chosen
• maybe a readme.md file with additional links and steps to consider?
