platform: nordic_nrf: ifdef out weak fault handlers

Default IRQ handlers will usually be overriden as they are weak. But
due to the way TF-M links it's binary (doesn't use whole-archive),
weak doesn't always work. So we explicitly ifdef out some IRQ handlers
that we know will be overridden by non-weak symbols anyway to be safe.
