Subject: [PATCH v4 4/8] x86/virt/tdx: Refine a comment to reflect the latest TDX spec

The old versions of "Intel TDX Module v1.5 ABI Specification" contain
the definitions of all global metadata field IDs directly in a table.

However, the latest spec moves those definitions to a dedicated
'global_metadata.json' file as part of a new (separate) "Intel TDX
Module v1.5 ABI definitions" [1].

Update the comment to reflect this.
