MdeModulePkg/PiSmmCore: AllocatePool should use MemoryType.

Browse Source 
PiSmmCore supports page level protection based upon the Memory Type
(EfiRuntimeServicesCode/EfiRuntimeServicesData) and PE image.

However, the Memory Type information is ignored in AllocatePool().
If a caller calls AllocatePool with EfiRuntimeServicesCode,
the final memory is still allocated as EfiRuntimeServicesData.

This patch supports AllocatePool with EfiRuntimeServicesCode.
