Tracking issue: https://github.com/bitcoin/bitcoin/issues/29018. The first commits adds an `ElapseSteady` helper and type aliases. The second commit uses those helpers in `ReportHeadersPresync` and in the fuzz target to increase determinism. ### Testing It can be tested via (setting 32 parallel threads): ``` cargo run --manifest-path ./contrib/devtools/deterministic-fuzz-coverage/Cargo.toml -- $PWD/bld-cmake/ $PWD/../b-c-qa-assets/fuzz_corpora/ p2p_headers_presync 32 ``` The failing diff is contained in the commit messages, if applicable.
