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

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.
