target/arc: skip over breakpoints in arc_resume()

When requested by the core code (handle_breakpoints = true),
arc_resume() should be able to advance over a potential breakpoint set
at the resume address instead of getting stuck in one place. This is
achieved by removing the breakpoint, executing one instruction,
resetting the breakpoint, then proceeding forward as normal.

With this patch applied, openocd is now able to resume from a
breakpoint halt when debugging ARCv2 targets via telnet.

This has previously been committed to the Zephyr project's openocd repo
(see https://github.com/zephyrproject-rtos/openocd/pull/31).
