Describe changes:

  • transforms: move strip_whitespace and compress_whitespace and dot_prefix to rust

Should we do all transforms ?

#11927 rebased to get green CI

Benchmark
./src/suricata -r bigf.pcapng -S bigf.rules -c bigf.yaml -k none -l log --runmode single
with big.rules being alert tcp any any -> any any (file.data; strip_whitespace; content:"hasxspace"; sid:1;) and bigf.pcapng being a capture of http1 download of 28 Mbyte file SV datasets-1m-StringSets/datasets.csv and bigf.yaml having all kinds of options for profiling

So 77389980 vs 81533120 does not seem significant for a difference
