stream-clone: allow to change persistent-nodemap format during stream clone
Persistent nodemap affect the store format. However it is fairly isolated and
fast to generate locally. So not making it a fixed part of the stream clone is
useful.
This allow clients without persistent-nodemap support (default for client
without Rust enabled, or simply older client). So it make it possible to enable
persistent nodemap on client, where it can provide a massive boost. without too
much consequence.
To do so, we stop using it in the advertisement requirements for streaming and
let the client add/remove the necessary file depending of its configuration.
We still send the files as it seems like a small save to not regenerate them.
In addition, the way we match them will overlap with the changelog-v2/revlog-v2
so we can't simply skip the associated patterns.
