The DXVA renderer SHOULD accept every format on Open(). We should NOT fall back to PS or SW rendering, ever, if the user chooses DXVA rendering.

DXVA is never auto-selected, it's always a user choice and it's usually for a reason (e.g. performance).

Either way, feel free to close this PR and revert #4163, I'll crawl back into my hole and add it as a private fix to my own builds again, just like I did in the past 2 years since this bug exists.
