Bug 1940282 [wpt PR 49954] - Add support for Ad-Auction-Result-Nonce …

…header for PA B&A, a=testonly

Automatic update from web-platform-tests
Add support for Ad-Auction-Result-Nonce header for PA B&A

Add support for the alternate authorization flow for Protected
Audiences Bidding and Auction response (as described in
WICG/turtledove#1233).

This feature is behind the FledgeBiddingAndAuctionNonceSupport
feature flag which is going to be enabled by default (for a
waterfall rollout in M133).
