Core LLM integration infrastructure to allow pgAdmin to connect to AI providers. #9641

* Core infrastructure for LLM integration.
* Add support for a number of different AI generated reports on security, performance, and schema design on servers, databases, and schemas, as appropriate.
* Add a Natural Language AI assistant to the Query Tool.
* Add an AI Insights panel to the EXPLAIN tool in the Query Tool, to analyse and report on issues in query plans.
