linux-user: Make semihosting heap/stack fields abi_ulongs 

The fields in the TaskState heap_base, heap_limit and stack_base
are all guest addresses (representing the locations of the heap
and stack for the guest binary), so they should be abi_ulong
rather than uint32_t. (This only in practice affects ARM AArch64
since all the other semihosting implementations are 32-bit.)
