James Tucker d0f3fa7d7e util/fastuuid: add a more efficient uuid generator 
This still generates github.com/google/uuid UUID objects, but does so
using a ChaCha8 CSPRNG from the stdlib rand/v2 package. The public API
is backed by a sync.Pool to provide good performance in highly
concurrent operation.

Under high load the read API produces a lot of extra garbage and
overhead by way of temporaries and syscalls. This implementation reduces
both to minimal levels, and avoids any long held global lock by
utilizing sync.Pool.
