UefiCpuPkg/MpInitLib: put mReservedApLoopFunc in executable memory
if PcdDxeNxMemoryProtectionPolicy is enabled for EfiReservedMemoryType
of memory, #PF will be triggered for each APs after ExitBootServices
in SCRT test. The root cause is that AP wakeup code executed at that
time is stored in memory of type EfiReservedMemoryType (referenced by
global mReservedApLoopFunc), which is marked as non-executable.
This patch fixes this issue by setting memory of mReservedApLoopFunc to
be executable immediately after allocation.
