UefiCpuPkg: Update SEC_IDT_TABLE struct
REF:https://bugzilla.tianocore.org/show_bug.cgi?id=3957
The reserved IDT table size in SecCore is too small for X64. Changed the type
of IdtTable in SEC_IDT_TABLE from UINT64 to IA32_IDT_GATE_DESCRIPTOR to have
sufficient size reserved in IdtTable for X64. dff
