UefiCpuPkg/MpInitLib: Add MP_ASSEMBLY_ADDRESS_MAP
In MpInitLibInitialize(), invoke AsmGetAddress() to get get assembly functions'
entry addresses and the sizes from returned MP_ASSEMBLY_ADDRESS_MAP structure.
v5:
1. Add more detailed comments for structure MP_ASSEMBLY_ADDRESS_MAP.
v4:
1. Add AsmRelocateApLoop information return in AsmGetAddress().
v3:
1. Rename AsmRellocateApLoop to AsmRelocateApLoop.
