DuetPkg: Use UefiCpuPkg/CpuDxe instead of DuetPkg/CpuDxe
UefiCpuPkg/CpuDxe provides all the critical features
needed for DUET. Therefore, to reduce code duplication,
DUET can use the generic UEFI CPU DXE driver.
The one notable lost feature is that DUET's CPU DXE would
call legacy video INT 10 to make sure the exception information
could be displayed on the screen.
