* improves sigverify discard_excess_packets performance (#22577)
As shown by the added benchmark, current code does worse if there is a
spam address plus a lot of unique addresses.

test bench_packet_discard_single_sender ... bench: 1,306,809 ns/iter (+/- 61,992)

* implements copy-on-write for staked-nodes (#19090)
Bank::staked_nodes and Bank::epoch_staked_nodes redundantly clone
staked-nodes HashMap even though an immutable reference will suffice:
https://github.com/solana-labs/solana/blob/a9014cece/runtime/src/vote_account.rs#L77
This commit implements copy-on-write semantics for staked-nodes by
wrapping the underlying HashMap in Arc<...>.

* Flip iter operations to keep associated address/header/packets together (#22245)
Flip iter operations to keep associated address/header/packets together
Before this change, if cast_socket_addr() returned a None for any
address/header pair, the subsequent zip() would misalign the
address/header pair and packet. So, this change zips all three together,
then does filter_map() so keep things aligned.
Additionally, compute total_size inline to avoid running through packets
a second time.

* removes epoch_authorized_voters from VoteTracker (#22192)
https://github.com/solana-labs/solana/pull/22169
verifies authorized-voter early on in vote-listener pipeline; and so
VoteTracker no longer needs to maintain and check for epoch authorized
voters.
