UefiCpuPkg/AcpiCpuData: Update RegisterTableEntry type 

Current RegisterTableEntry filed in CPU_REGISTER_TABLE is one pointer to
CPU_REGISTER_TABLE_ENTRY. If CPU register table wants to be passed from 32bit
PEI to x64 DXE/SMM, x64 DXE/SMM cannot get the correct RegisterTableEntry.

This update is to update RegisterTableEntry type to EFI_PHYSICAL_ADDRESS and
make RegisterTableEntry is fixed length.
