qHash: implement chunked hashing of QLatin1StringView
So that it hashes to the same value as QString{,View}.
In order to test this, you must either run on a CPU other than ARM and
x86, or disable the AES hasher. I did that and can confirm siphash and
murmurhash do work with on-the-fly conversion from Latin-1.
