zephyr: use 64-bit cycle counter for benchmarks
cf52cfb 
Zephyr's k_cycle_get_32() can wrap during long NUCLEO benchmark windows, producing huge unsigned deltas in the benchmark output. Use k_cycle_get_64() for Zephyr targets.

Also make ML-DSA benchmark percentile sorting and formatting robust for large uint64_t cycle values.

I've marked this PR as a draft because while MVE memset/memcpy/zeroize did have a positive impact on reducing key pair generation, it had the opposite effect on signature generation and verification. This should not be the case and was not the case when I added it in local testing. However, I added it after other assembly optimisations, not before. Therefore, I'll defer this one until it makes an improvement in all benchmarks.
