feat: set branch in same state as it used to be

[MarioJGMsoft]

Description

This PR is a follow up to #27126; it tags high volume FluidFramework telemetry events as LogLevel.info. The goal is to let clients safely filter out info-tagged events without losing the signal needed to diagnose Fluid issues.

Events were selected by observed telemetry volume and span both generic and performance events. For consumers today, the only observable difference is that tagged events now carry logLevel: "info" on their payload - no filtering or delivery behavior changes were made.

Reviewer Guidance

The review process is outlined on this wiki page.

• Each taggeed event has a PR comment specifying which event is being marked as info. The authors have been identified via git blame and tagged on the corresponding PR comment - please confirm info is correct for events that you have context on. If it is correct, please resolve the comment to know that I can go forward with the change.
• If you don't have context on the event, please point me to who could know more about the event.
• If you see an event in the diff you believe should remain untagged, flag it.
• With the addition of the LogLevel.info parameter the formatting for various pieces of the code was updated. I highly recommend turning on the hide whitespace changes option when reviewing this PR.

Fixes: AB#52417
