outgoing: add a simple fastpath when there is no common

This further speed up case like `hg bundle --all` for larger repository.

### data-env-vars.name            = mozilla-try-2023-03-22-zstd-sparse-revlog
  # benchmark.name                = hg.command.bundle
  # bin-env-vars.hg.flavor        = default
  # bin-env-vars.hg.py-re2-module = default
  # benchmark.variants.revs       = all
  # benchmark.variants.type       = none-streamv2
before: 316.749699
after:  311.165461   (-1.76%, -5.58)


There is further work to be done in this area like not doing any outgoing
computation in the stream case for example. however the recent changes already
gives use a large win for a small amount of local work.

  # benchmark.variants.revs       = all
  # benchmark.variants.type       = none-streamv2
