When DXE drivers are dispatched above 4GB memory in 64bit
mode, the address setCodeSelectorLongJump in stack will
be override by parameter. Jump to Qword is not supported
by some processors. So use "o64 retf" instead.

When DXE drivers are dispatched above 4GB memory and
the system is already in 64bit mode, the address
setCodeSelectorLongJump in stack will be override
by parameter. so change to use 64bit address and
jump to qword address.

Current implementation not checks system mode before using
PAGE_TABLE_LIB_PAGING_CONTEXT.ContextData.X64 or
PAGE_TABLE_LIB_PAGING_CONTEXT.ContextData.Ia32. This patch check the
mode before using the correct one.

NASM has replaced ASM and S files.
1. Remove ASM from all modules expect for the ones in ResetVector directory.
The ones in ResetVector directory are included by Vtf0.nasmb. They are
also nasm style.
2. Remove S files from the drivers only.
3. https://bugzilla.tianocore.org/show_bug.cgi?id=881
After NASM is updated, S files can be removed from Library.

The AP startup code simply jumps into this code with the CpuDxe driver
without setting up a stack for the processor.
Therefore, this code must setup the stack before calling into C code.
This is the basic flow:
* AP enters CpuDxe driver code (AsmApEntryPoint) without stack
- AP grabs a lock
- AP sets up stack
- AP calls CpuMp.c:ApEntryPointInC
- If ApEntryPointInC returns, the lock is freed, and another AP may
run
- The AP C code may call AsmApDoneWithCommonStack to indicate that
the AP is no longer using the stack, and another may therefore
proceed to use the stack and then call ApEntryPointInC
