Merge bitcoin/bitcoin#22284: p2p, refactor: performance improvements to ProtectEvictionCandidatesByRatio() 
b1d905c225e87a4a289c0cd3593c6c21cea3fba7 p2p: earlier continuation when no remaining eviction candidates (Vasil Dimov)
c9e8d8f9b168dec2bc7b845da38449e96708cf8e p2p: process more candidates per protection iteration (Jon Atack)
02e411ec456af80d1da76085a814c68bb3aca6de p2p: iterate eviction protection only on networks having candidates (Jon Atack)
5adb06457403f8c1d874e9c6748ecbb78ef8fa2b bench: add peer eviction protection benchmarks (Jon Atack)
566357f8f7471f74729297868917aa32f6d3c390 refactor: move GetRandomNodeEvictionCandidates() to test utilities (Jon Atack)

Pull request description:

  This follow-up to #21261 improves `ProtectEvictionCandidatesByRatio()` for better performance.

  Benchmarks are added; the performance improvement is between 2x and 5x for the benchmarked cases (CPU 2.50GHz, Turbo off, performance mode, Debian Clang 11 non-debug build).

  ```
  $ ./src/bench/bench_bitcoin -filter="EvictionProtection*.*"
  ```

  The refactored code is well-covered by existing unit tests and also a fuzzer.

  - `$ ./src/test/test_bitcoin -t net_peer_eviction_tests`
  - `$ FUZZ=node_eviction ./src/test/fuzz/fuzz ../qa-assets/fuzz_seed_corpus/node_eviction`

Test library

This contains files for the test library, which is used by the test binaries (unit tests, benchmarks, fuzzers, gui tests).

Generally, the files in this folder should be well-separated modules. New code should be added to existing modules or (when in doubt) a new module should be created.

The utilities in here are compiled into a library, which does not hold any state. However, the main file setup_common defines the common test setup for all test binaries. The test binaries will handle the global state when they instantiate the BasicTestingSetup (or one of its derived classes).
