Revert "Implement support for bidNonce and seller nonces"

This reverts commit 803a93609b702479399a8376bd90b1d7780d2794.

Reason for revert: Deterministic failures of browser tests linked to the seller nonce on the bots.

E.g.

Original change's description:

Implement support for bidNonce and seller nonces

Introduce a mechanism that allows sellers to avoid giving the same nonce
to all buyers, since this can be used to determine that these buyers are
in the same auction. Instead, a new nonce is given to each buyer based
on the SHA-256 combination of both the auctionNonce and a new seller
nonce, which is given to the browser, but not to buyers.

The browser can verify the bidNonce from bids by computing the expected
bidNonce for a given auctionNonce and seller nonce, thus preserving the
existing replay protections of the auctionNonce.
