Merge bitcoin/bitcoin#31045: ci: Add missing -DWERROR=ON to test-each-commit

fa1cffa ci: Install missing nproc in macos task (MarcoFalke)
faf7a2b ci: Add missing -DWERROR=ON to test-each-commit (MarcoFalke)

Pull request description:

  Found by in Sjors in bitcoin/bitcoin#27260 (comment) (Thanks!)

  Also, includes an unrelated commit to simplify the ci scripts, by assuming nproc exists on macos as well. (Having more than one commit is also required to trigger the `test-each-commit` task)
