Pull request description:
Derived from #28120 discussion.
By relocating the peer desirable services flags into the peer manager, we
allow the connections acceptance process to handle post-IBD potential
stalling scenarios.
The peer manager will be able to dynamically adjust the services flags
based on the node's proximity to the tip (back and forth). Allowing the node
to recover from the following post-IBD scenario:
Suppose the node has successfully synced the chain, but later experienced
dropped connections and remained inactive for a duration longer than the limited
peers threshold (the timeframe within which limited peers can provide blocks). In
such cases, upon reconnecting to the network, the node might only establish
connections with limited peers, filling up all available outbound slots. Resulting
in an inability to synchronize the chain (because limited peers will not provide
blocks older than the `NODE_NETWORK_LIMITED_MIN_BLOCKS` threshold).
