feat(qemu): hand off TPM event log via TL

Browse source 
If TRANSFER_LIST is enabled, hand off TPM event log via TL instead
of DT; otherwise fallback to legacy way if TRANSFER_LIST is off or
errors observed.

Moreover, for updating the TL from secure to non-secure
memory before existing EL3, replace memcpy with function
transfer_list_relocate() for more accuracy.
