UefiCpuPkg/CpuDxe: Add ApEntryPointInC

This is the function the AP assembly code will expect to call after
getting a lock and setting up the stack.

Only one AP will enter this routine at a time.

If ApEntryPointInC exits, then the assembly code will loop around to
grab the lock, setup the stack, and call ApEntryPointInC again.

UefiCpuPkg/CpuDxe: Add stackless assembly AP entry points

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

Note: It seems previously we were not using '#pragma pack ()' in
