UefiCpuPkg/CpuMp: Fix hang when StackGuard is enabled in 16-core cpu
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3167
When StackGuard is enabled, the CpuMp driver allocates
known good stacks for all CPUs for DF# and PF# exceptions.
It uses AllocatePool to do so.
The size needed equals to 64KB
= StackSize (2K) * ExceptionNumber (2) * NumberOfProcessors (16)
However, AllocatePool max allocation size is less than 64K.
To fix the issue, AllocatePages() is used.
