Taylor Blau cc2a1f98ac builtin/receive-pack.c: avoid enumerating hidden references
Now that `refs_for_each_fullref_in()` has the ability to avoid
enumerating references matching certain pattern(s), use that to avoid
visiting hidden refs when constructing the ref advertisement via
receive-pack.

Note that since this exclusion is best-effort, we still need
`show_ref_cb()` to check whether or not each reference is hidden or not
before including it in the advertisement.

As was the case when applying this same optimization to `upload-pack`,
`receive-pack`'s reference advertisement phase can proceed much quicker
by avoiding enumerating references that will not be part of the
advertisement.

(Below, we're still using linux.git with one hidden refs/pull/N ref per
commit):

    $ hyperfine -L v ,.compile 'git{v} -c transfer.hideRefs=refs/pull receive-pack --advertise-refs .git'
    Benchmark 1: git -c transfer.hideRefs=refs/pull receive-pack --advertise-refs .git
      Time (mean ± σ):      89.1 ms ±   1.7 ms    [User: 82.0 ms, System: 7.0 ms]
      Range (min … max):    87.7 ms …  95.5 ms    31 runs

    Benchmark 2: git.compile -c transfer.hideRefs=refs/pull receive-pack --advertise-refs .git
      Time (mean ± σ):       4.5 ms ±   0.2 ms    [User: 0.5 ms, System: 3.9 ms]
      Range (min … max):     4.1 ms …   5.6 ms    508 runs

    Summary
      'git.compile -c transfer.hideRefs=refs/pull receive-pack --advertise-refs .git' ran
       20.00 ± 1.05 times faster than 'git -c transfer.hideRefs=refs/pull receive-pack --advertise-refs .git'
