From: Min M Xu <min.m.xu at intel.com>
RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3937
In lazy-accept the MaxAcceptedMemoryAddress is needed in
TransferTdxHobList and ContructFwHobList(at PeilessStartupLib). But in
SEC phase we cannot use a global variable to pass this value. So we add
a new field (MaxAcceptedMemoryAddress) in Tdx work area.
