modules: hal_nordic: nRF 802.15.4 customizable asserts

Recent nRF 802.15.4 Radio Driver provides assert abstraction layer.
The assert abstraction layer is implemented in Zephyr in following
ways depending on the `NRF_802154_ASSERT_CHOICE` Kconfig choice.

`NRF_802154_ASSERT_ZEPHYR_MINIMAL` (default) gives ability to still
perform run-time checking of the nRF 802.15.4 Radio Driver operation
with minimum memory overhead and configurable behavior on fault
detection regardless of the `CONFIG_ASSERT` Kconfig option value.

`NRF_802154_ASSERT_ZEPHYR` gives ability to use asserts provided and
configurable by Zephyr including the ability to turn off the run-time
checking of the nRF 802.15.4 Radio Driver operation.
