[PATCH] D155992: [clangd] Use xxh3_64bits for background index file digests

sammccall added a comment.

These hashes are used in the filenames of index shards, and in the metadata describing dependencies between shards.

So this is an incompatible change to indexing format, you also need to increment `constexpr static uint32_t Version` in Serialization.cpp:460.

(I think this is fine, but not stamping just yet as I want to sync with Kadir on monday - I don't think we have anything that GCs the old shards but probably that shouldn't block this change)
