Add some performance metrics for Sentry (#5760)

- Add `AnalyticsService.startTransaction(...)` to start a logging transaction that can be uploaded to Sentry if the user enabled the analytics upload.
- Add `AnalyticsTransaction` wrapper to abstract the Sentry ones.
- Added several helper methods to improve the UX around these transactions.
- Then measure:
  - Time until the first sync, and how it ended.
  - Time until the first rooms are displayed.
  - Time to load a room or a preview.
  - Time to load a timeline.
