p2p/discover: refactor node and endpoint representation (#29844 )

Here we clean up internal uses of type discover.node, converting most code to use
enode.Node instead. The discover.node type used to be the canonical representation of
network hosts before ENR was introduced. Most code worked with *node to avoid conversions
when interacting with Table methods. Since *node also contains internal state of Table and
is a mutable type, using *node outside of Table code is prone to data races. It's also
cleaner not having to wrap/unwrap *enode.Node all the time.

discover.node has been renamed to tableNode to clarify its purpose.

While here, we also change most uses of net.UDPAddr into netip.AddrPort. While this is
technically a separate refactoring from the *node -> *enode.Node change, it is more
convenient because *enode.Node handles IP addresses as netip.Addr. The switch to package
netip in discovery would've happened very soon anyway.

The change to netip.AddrPort stops at certain interface points. For example, since package
p2p/netutil has not been converted to use netip.Addr yet, we still have to convert to
net.IP/net.UDPAddr in a few places.

p2p/discover: concurrent TALKREQ handling (#27112 )

This changes TALKREQ message processing to run the handler on separate goroutine,
instead of running on the main discv5 dispatcher goroutine. It's better this way because
it allows the handler to perform blocking actions.

I'm also adding a new method TalkRequestToID here. The method allows implementing
a request flow where one node A sends TALKREQ to another node B, and node B later
sends a TALKREQ back. With TalkRequestToID, node B does not need the ENR of A to
send its request.
