andrewfish 271d2c7f99 EdkCompatabilityPkg: Fix build issues with X64 clang 
Removed passing VA_LIST and some assembly language compatability issues. Did not fix ReportStatusCode passing VA_LIST (non-ANSI C Code), and some of the assembler was not not ported and int 3 was inserted, as it likely is not needed.

jgong5 ff443d3ebd Use on-demand paging for CpuSaveStates read/write. It was measured about 200us for either read or write the PI CpuSaveStates to framework, ~400us in total on a platform with 80 CPUs with original for loop implementation. So with on-demand paging, if the framework SMI handler doesn’t read/write CpuSaveStates, ~400us will be saved. If the handler happens to use CpuSaveStates, there will be about 20us overhead for either read or write a page which contains 5 continuous CpuSaveStates.
