sessions: add telemetry for Agents window interactions

Add GDPR-compliant telemetry events for user interactions in the Agents
window. All event types and logging helpers are centralized in
sessionsTelemetry.ts.

Titlebar buttons (vscodeAgents.interaction): newSession, runPrimaryTask,
addTask, generateNewTask, openTerminal, openInVSCode.

Changes panel: togglePanel, versionModeChange, fileSelect,
reviewCommentAdded.

Fixes microsoft/vscode-internalbacklog#7256
Fixes microsoft/vscode-internalbacklog#7257
