better logging for trigger-more-eagerly autocomplete (#273)

Instruments our existing autocomplete logging to better track the new
trigger-more-eagerly behavior introduced in #260:

1. Whether user has the
`cody.autocomplete.experimental.triggerMoreEagerly` setting enabled.
1. Whether the completion was shown only because of that setting.

## Test plan

n/a; for experimental feature only
