Switch networking crates to Rust 2024 edition

[kskalski]

Problem

Rust 2024 migration is now possible for monorepo. Most of the code do not have any semantic changes and is only affected by formatting style switch, some exceptions do exist, mostly in order of drops, which should be reviewed, e.g. w.r.t. possible locking behavior change.

The semantic changes (caused by if-let-rescope, tail-expr-drop-order, edition-2024-expr-fragment-specifier) can be detected running cargo fix --edition and in case of this PR they generate a few cases as attached below

cargo +nightly-2025-09-14 fix --edition -p solana-bloom -p solana-gossip -p solana-net-utils -p solana-tls-utils -p solana-turbine 

yields
networking_tail_expr.txt
networking_expr_fragment.txt
networking_if_let_rescope - no code has semantic changes

Summary of Changes

• switch crates owned by networking (without parts of core) to Rust 2024 edition
• update formatting per 2024 style
• fix collapsible if warnings

Note: styling change can be decoupled from switching edition, but it can only be done for the whole workspace and be done shortly before new release cut

Reviewing

Probably the best way to review is to git diff -w individual commits or possibly re-generate this PR locally to see for identical results from:

• cherry-pick e0f81b1 (edition switches)
• cargo +nightly-2025-09-14 fmt --all
• cargo +nightly-2025-09-14 clippy --workspace --all-targets --fix --features dummy-for-ci-check,frozen-abi -- --deny=warnings --deny=clippy::default_trait_access --deny=clippy::arithmetic_side_effects --deny=clippy::manual_let_else --deny=clippy::uninlined-format-args --deny=clippy::used_underscore_binding - collapsible if fix
