Maybe it's better to split this patch into two, one to read generic "TDX
Module Extension" related global metadata, and the other to read TDX Connect
specific ones?

They are logically two separate things anyway. And there are other features
also need to enable TDX Module Extensions (e.g., NRX for migration), and we
can just reuse the generic metadata patch from this series.
