Per @zumwalt's suggestion, we could use @supports to provide a fallback for IE11.

I don't think, at this point, it makes sense to replace EuiFlexGrid with CSS grid and instead it would probably be a whole other component (that no one has requested yet). So I'm going to close this issue out until someone does.
