Jian J Wang 41a9c3fd11 UefiCpuPkg/CpuDxe: remove all code to flush TLB for APs
The reason doing this is that we found that calling StartupAllAps() to
flush TLB for all APs in CpuDxe driver after changing page attributes
will spend a lot of time to complete. If there are many page attributes
update requests, the whole system performance will be slowed down
explicitly, including any shell command and UI operation.

The solution is removing the flush operation for AP in CpuDxe driver
and let AP flush TLB after woken up.
