[FLEDGE] Add WPT test for ties.

In the case two bids have the same score, either interest group can win
an auction. This adds a single test to make sure that two interest bids
with the same score can each win an auction. This doesn't check that
they each win half the time (since tesing random number generators is
involved an slow).

To make the test run in reasonable time, it uses a component auction.
The inner auction has two IGs with the same score, and the outer
auction rejects ads from an interest group that has already won an
auction (updating the script to do this after one group has won).
This avoids needing to load the winning ad in a fenced frame each
time there's a winner, which is potentially slow, and allows auctions
to be run in parallel.
