Currently running "make V=1 flash/debug" does not result in the caller discovering what commands are run to perform the action because make calls into an opaque script (which then makes complex invokations of both openocd and gdb). Make the script more transparent by conditionally enabling enabling tracing within the script. We also remove the "Done flashing" message. It is pointless because openocd has already *told* us it has done flashing ["wrote 16384 bytes from file .../zephyr.elf in 0.802135s (19.947 KiB/s)"]. It is also potentially misleading since it tells us we are "Done flashing" even when we failed to flash anything which risks misleading someone unfamiliar with openocd.
