Jacques Lucke e2d170f685 Libraries: integrate xxHash library for fast hashing
`xxHash` is a fast non-cryptographic hashing library. It significantly outperforms
md5 which we use in some places currently while also having great collision
resistance if not attacked explicitly.

The library is added to `extern` because that was the easiest way to do it and has
the least impact on others. I expect this library to become a required dependency
instead of an optional one. It's licence is `BSD 2-Clause` which seems to be the
first of its kind in Blender (there is `BSD 3-Clause` a couple of times).

For now, I used the library only for data deduplication when baking geometry nodes
where the same geometry is generated for each frame. The bake time in my test
goes down from >6s to <1s (note that this includes more than just the hashing time).
