hash: Add MurmurHash3 with streaming support

The implementation is based on the upstream PMurHash. The following
variants are implemented

- murmur3a, 32-bit hash
- murmur3c, 128-bit hash for x86
- murmur3f, 128-bit hash for x64

The custom seed support is not targeted by this implementation. It will
need a major change to the API, so then custom arguments can be passed
through `hash_init`. For now, the starting hash is always zero.

Fixes bug #68109, closes #6059
