Add auto-approval messages for global chat.tools.autoApprove setting

[Copilot]

When the global "chat.tools.autoApprove": true setting is enabled, terminal commands are automatically approved and executed without user confirmation. However, users were not informed why the command was auto-approved, leaving them without context about the automatic execution.

This change adds clear messaging to inform users when commands are auto-approved due to the global setting:

Before: Commands auto-approved by the global setting showed no explanation
After: Commands show "Auto approved by global tools setting" message

Changes Made

1. Enhanced Auto-Approval Detection (languageModelToolsService.ts)

• Modified shouldAutoConfirm() to return detailed information about the auto-approval source
• Added logic to set autoApproveInfo in terminal tool data when the global setting triggers auto-approval
• Preserves existing terminal-specific auto-approval messages (they take precedence over global messages)

2. Updated Message Display (chatTerminalToolProgressPart.ts)

• Modified content rendering to include autoApproveInfo when present
• Ensures the auto-approval message appears below the command in the chat interface

Behavior

• When "chat.tools.autoApprove": true is set, users now see a clear message explaining the auto-approval
• Terminal-specific auto-approval rules continue to work as before and show their own messages
• No changes to auto-approval functionality - only adds user-facing messaging for transparency

The fix ensures users understand when and why their commands are being automatically executed, improving the overall user experience and transparency of the auto-approval system.

Fixes #261319.
