chore(vac): remove support for Verifiable Ad Conversions (#1622)

VAC has not been used by any campaigns for over 18 months. We are
decommissioning support for this as first party analytics options have
greatly improved.

Remove:
- ability to configure the advertiser public/private keys
- ability to download and decrypt the VAC report
