fix(gossipsub): fix inconsistent publish to floodsub peers

[turuslan]

Description

publish broadcasted to all floodsub peers regardless of their topics

Notes & open questions

publish broadcasted to all floodsub peers regardless of their topics when config.flood_publish = false.
config.flood_publish = true publishes to subscribed peers only.
rust-libp2p floodsub publishes message to subscribed peers only (code).
go-libp2p-pubsub gossipsub publishes message to subscribed peers only (code).
This PR reduces messages count, while #5908 increases it, so I thought they can be reviewed independently.
