[PATCH 4/6] OvmfPkg/Sec: Install MpInitLibDepLib PPIs in SecMain.c

["Min Xu" <min.m.xu@intel.com>]

From: Min M Xu <min.m.xu@intel.com>

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

Td guest should use MpInitLibUp, other guest use the MpInitLib. So
in SecMain.c different PPI is installed according to the working
guest type.
