This option will create a vector table which only contains NMI and HardFault vectors, and a single bkpt instruction for them to point to. I believe that this is the smallest size vector table that can be used safely with RP2350, as the NMI and HardFault interrupts cannot be disabled, and by default BusFaults etc all escalate to HardFaults so don't require separate vectors.
When this is enabled you cannot use any interrupts - I haven't disabled them as I wasn't sure of the best way to do that, but I've mentioned that in the PICO_CONFIG comment.
This supercedes #2200
