Original change's description:
> Enable 5 Protected Audience and Fenced Frame features in Mode A/B
>
> With the end of the Chrome-facilitated testing period, enable these features
> in Modes A and B to provide a more consistent developer experience and
> decrease the need for feature detection:
>  * PA Real Time Reporting
>  * PA multi-bid support
>  * PA deprecatedReplaceInURN via auction config
>  * PA multiple bidding contexts optimization
>  * FF allow cross-origin subframes to send reportEvent() beacons
>
