crypto/kzg4844: add helpers for versioned blob hashes (#28827)

Browse Source 
The code to compute a versioned hash was duplicated a couple times, and also had a small
issue: if we ever change params.BlobTxHashVersion, it will most likely also cause changes
to the actual hash computation. So it's a bit useless to have this constant in params.
