BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3918

Above BZ reports an issue that commit 88da06ca triggers ASSERT in some
scenario. This patch-set is to fix this issue.

As commit 88da06ca describes TDVF BSP and APs are simplied and it can
simply use MpInitLibUp instead of MpInitLib. To achieve this goal, we
include 2 CpuMpPei/CpuDxe drivers in OvmfPkgX64 and IntelTdxX64. This
is done by setting different FILE_GUID to these drivers (of the same
name). In the other hand, we import a set of MpInitLibDepLib. These
libs simply depend on the PPI/Protocols. While these PPI/Protocols are
installed according to the guest type.

This patch-set is a replacement of
