UefiCpuPkg: Duplicated AsmRelocateApLoop as AsmRelocateApLoopAmd
AsmRelocateApLoop is replicated for future Intel Logic Extraction,
further brings AP into 64-bit, and enables paging.

Log Message:
-----------
UefiCpuPkg: Has APs in 64 bit long-mode before booting to OS.
During the finalization of Mp initialization before booting into the OS,
depending on whether Mwait is supported or not, AsmRelocateApLoop
places Aps in MWAIT-loop or HLT-loop.
Since paging is necessary for long mode, the original implementation of
moving APs to 32-bit was to disable paging to ensure that the booting
does not crash.
The current modification creates a page table in reserved memory,
avoiding switching modes and reclaiming memory by OS. This modification
is only for 64 bit mode.
More specifically, we keep the AMD logic as the original code flow,
extract and update the Intel-related code, where the APs would stay
in 64-bit, and run in a Mwait or Hlt loop until the OS wake them up.
