Sample 4 fit and finish (synchronous chat loading states, tool tips, sorted model dropdowns, dependency gates)

[teresaqhoang]

Motivation and Context

1. Enabling multiple loading states for synchronous chat
2. Added informational tooltip about relevance
3. Updated scroll check (scolls anytime response or chatHistory is updated)
4. Sorted model options dropdown in Completion and Embeddings Model Setup
5. Disable Embeddings config page if completion model hasn't been set (If completion hasn't been set, SK invoke will fail)

Description

Models dropdown is split into 2 sections sorted alphabetically: "Suggested" and "Others", where Suggested is populated based on common naming conventions, where

• Probable Embeddings Models contain "embedding" or "search"
• All others are considered probable Completion Models
