ArmPlatformPkg/PrePi: Use the same calculation to declare the stack size as in the entrypoint
The stack size in the entrypoint (ie: $ARCH/ModuleEntryPoint.S) is calculated such as
StackSize = PrimaryCoreStack + (core_count - 1) * SecondaryCoreStack
While we were declaring the stacksize into the stack hob as:
StackSize = PrimaryCoreStack + (cluster * 8) * SecondaryCoreStack
If the number of cluster (ie: PcdClusterCount) were not defined correctly then
the stack size declaration were not correct.
It could cause stack corruption if the allocator allocates memory in this range.
