Add assembly code for AP reset vector and the definition of MP_CPU_EXCHANGE_INFO
that are used to exchange the data between C code and assembly code when AP wake
up.
v4:
1. Copy MP_CPU_EXCHANGE_INFO from UefiCpuPkg/CpuMpPei/CpuMpPei.h
2. Copy MpEqu.inc and MpFuncs.nasm from UefiCpuPkg/CpuMpPei.
v3:
1. Rename NumApsExecutingLoction to NumApsExecutingLocation
2. Add whitespace after ; in .nasm file
