add hide-elevate-button-in-accept-window (#16271)

A portable client handed to standard users offers them "Accept and Elevate",
which they have no credentials to complete. The builtin option takes that
button out of the accept window and leaves elevation to the controlling
side's "Request Elevation" during the session.
