In a similar fashion as in previous commits, teach `ls-refs` to avoid
enumerating hidden references where possible.
As before, this is linux.git with one hidden reference per commit.
$ hyperfine -L v ,.compile 'git{v} -c protocol.version=2 ls-remote .'
Benchmark 1: git -c protocol.version=2 ls-remote .
Time (mean ± σ): 89.8 ms ± 0.6 ms [User: 84.3 ms, System: 5.7 ms]
Range (min … max): 88.8 ms … 91.3 ms 32 runs
