Ceping Sun d997d3c62f OvmfPkg: Use TdHob instead of e820tables to get memory info in TDVF ...

Currently, TDVF gets LowMemory and FistNonAddress from the e820tables
via fw_cfg, while TD-Hob can also provide the memory info of LowMemory
and FistNonAddress.

In current stage e820tables are not measured but TD-Hob is measured in
early phase by TDVF.

So, from the security perspective we'd better use the information from
TD-Hob instead of e820tables.
