Add private get_memory_properties() syscall which allows one to retrieve the

address protection bits as well as the wiring flags for an arbitrary address
in a team's address space. Will be used in the debugger for the purposes
of the memory inspector/editor, in order to determine whether it can in fact
allow editing for the currently inspected address range.
