Driver version mismatch should blacklist any graphics features
We're currently blocking an arbitrary bunch of graphics features when there's driver mismatches. We should block all of them since we really have no idea what driver is installed.

Jeff, Bas, could you land this patch and ask for the uplift requests? Thanks
Comment on attachment 8516785 [details] [diff] [review] Don't allow any features when there's a driver version mismatch Approval Request Comment [Feature/regressing bug #]: [User impact if declined]: Some users with driver mismatch fallback to D3D9 even though we don't know if their driver can handle D3D9 propely (due to the fact that we can't tell what driver they have). As a result some user can endup with unsupported configurations such as D2D+D3D9 or D3D9 outside of windows xp. [Describe test coverage new/current, TBPL]: None. [Risks and why]: very low, it gets user with unknown configuration (driver version mismatch) to software rendering which is the safest place they can be. [String/UUID change made/needed]: None.

This unintentionally blocked all acceleration on Windows XP on Intel hardware.
