target/arc: restore breakpoints in arc_resume()
Presently, we rely on gdb to restore break/watchpoints upon resuming execution in arc_resume(). To match this behavior in absence of gdb (more specifically, when handle_breakpoints is true), this patch explicitly re-enables all breakpoints and watchpoints in arc_resume(). This has previously been committed to the Zephyr project's openocd repo (see https://github.com/zephyrproject-rtos/openocd/pull/31).
