OvmfPkg: Use TdInfo instead of fw_cfg to get cpu count in TDVF
Currently TDVF gets cpu count information via fw_cfg, but
this information can also be retrieved by calling of TdCall.TdInfo.
And TdCall is responded by tdx-module which is trust.
So, from the security perspective we shall use TdCall.Tdinfo instead
of fw_cfg.
