telemetry: Reduce the amount of telemetry events fired (#36060)

1. Extension loaded events are now condensed into a single event with a
Vec of (extension_id, extension_version) called id_and_versions.
2. Editor Saved & AutoSaved are merged into a singular event with a type
field that is either "manual" or "autosave”.
3. Editor Edited event will only fire once every 10 minutes now.
4. Editor Closed event is fired when an editor item (tab) is removed
from a pane
