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

Add two MP Initialize Library instances PeiMpInitLib.inf and DxeMpInitLib.inf with NULL implementation. One PeiMpInitLib.inf is consumed by PEI MP driver. Another DxeMpInitLib.inf is consumed by DXE

MP Initialize library provides basic functionalities to do APs initialization, to manage MP information and to wakeup APs to execute AP task. It could be consumed by CPU MP PEI or DXE drivers to

Currently, we will allocate StartupVector buffer under 1MB at entry point function. But some modules may allocate some hard code address under 1MB. For example, LegacyBiosDxe driver tries to manage

We add MP Initialize Library defined in UefiCpuPkg/Include/Library/MpInitLib.h. It will provide basic functionalities of MP services and could be consumed by CPU MP PEI and CPU MP DXE to produce CPU
