x86/tdx: Dump attributes and TD_CTLS on boot
Dump TD configuration on boot. Attributes and TD_CTLS define TD
behavior. This information is useful for tracking down bugs.
The output ends up looking like this in practice:
[ 0.000000] tdx: Guest detected
[ 0.000000] tdx: Attributes: SEPT_VE_DISABLE
[ 0.000000] tdx: TD_CTLS: PENDING_VE_DISABLE ENUM_TOPOLOGY VIRT_CPUID2 REDUCE_VE
