modules: hal_nordic: Integrate nrf-regtool 7.0.0

This new version introduces a new sub-command `uicr-compile`, which will
generate `uicr.hex` based on a new binary format required by an upcoming
release of Secure Domain Firmware (SDFW) closer to production.

Since this is a breaking change, and SDFW is not finalized yet, we need
to support two nrf-regtool versions for a short time, and use different
CLI invocations based on which version is installed. Hence, the minimum
required version is unchanged.

Additionally, retire CONFIG_NRF_REGTOOL_EXTRA_GENERATE_ARGS. There will
be no use for it moving forward.
