Enable ARM-only semihosting mode. This mode allows applications on the Pico to write to the OpenOCD console and read and write files on the host system (i.e. debugging dump information, etc.) It is not very fast because of the way it uses breakpoints on the Pico to communicate, but it is useful in cases when you want to get a single file off of the Pico while debugging. Note that this **requires** a connected OpenOCD and GDB or else the semihosting will cause a system panic.
