Eliminate authenticated_caller_id from the OperationContext (#4371)

## Motivation

It is not used and not set to any other value than `None`.

## Proposal

Straight removal.
I am not 100% sure, but I think that it is not an error that it is not
used.
The `authenticated_caller_id` is instead available via the call_stack.

## Test Plan

The CI.

## Release Plan

- Nothing to do / These changes follow the usual release cycle.

## Links

None.
