MdeModulePkg/Core/Dxe: Initialize GCD before RT memory allocations 

Update the DxeMain initialization order to initialize GCD
services before any runtime allocations are performed.  This
is required to prevent runtime data fragmentation when the
UEFI System Table and UEFI Runtime Service Table are allocated
before both the memory and GCD services are initialized.
