Support reporting k-anon failures to FLEDGE extended PA reporting

Adds support for k-anon failures as a bid-reject-reason for FLEDGE
extended Private Aggregation reporting (as specified in
https://github.com/WICG/turtledove/blob/main/FLEDGE_extended_PA_reporting.md
). Reporting requests that use the bid-reject-reason as a baseValue
will be sent if the only reason the corresponding bid was not the winner
of an auction was because the bid specified a creative that was not
k-anonymous (i.e. if k-anonymity were not enforced they would have been
the auction winner). Note that other reporting requests will still be
honored, so if the interest group made a second bid as a fall-back but
that bid lost it is possible to receive a report specifying the
bid-reject-reason for that bid as well.
