OvmfPkg: Introduce lazy accept in PlatformInitLib and PlatformPei

RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3937

There are below major changes in PlatformInitLib/PlatformPei
1. ProcessHobList
  The unaccepted memory is accepted if it is under 4G address.
  Please be noted: in current stage, we only accept the memory under 4G.
  We will re-visit here in the future when on-demand accept memory is
  required.

2. TransferTdxHobList
  Transfer the unaccepted memory hob to EFI_RESOURCE_SYSTEM_MEMORY hob
  if it is accepted.
