ArmPkg/AsmMacroIoLib: Fixed the global variables initialization
The top of the stack always points to 'stack_base + stack_size'.
But the stack pointer is decremented before writing to the stack.
It means the top byte of the stack is actually 'stack_base + stack_size - 1'.
The initialization should also decrement the stack pointer before
zero'ing the memory (pre-indexed addressing).
