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 driver.

Place MpInitLibStartupAllAPs()/MpInitLibStartupThisAp()/MpInitLibSwitchBSP()/
MpInitLibEnableDisableAP() into PeiMpLib.c and DxeMpLib.c, because they have
the different implementations and will be updated in latter patches.

v4:
1. Return EFI_UNSUPPORTED instead of EFI_SUCCESS for NULL implementation of
all Functions.
2. Sync MpInitLibxxx functions header updating described in v4 part of Patch
#4.

v3:
1. Rename MpInitLibSwitchBsp to MpInitLibSwitchBSP to match PI spec
