Subject: [PATCH] x86/coco: Update comment of CC_ATTR_GUEST_MEM_ENCRYPT to include TDX guest

TDX guest also reports CC_ATTR_GUEST_STATE_ENCRYPT as true, but the
comment of this attribute does not reflect this.

Update the comment to reflect the fact.

Alternatively, we can just drop all these "Examples include ...". The same
info can easily can be derived from code.
