bherbruck ead02a9ec1 ci: cut CI wall time (parallel jobs, opt-level 0 difftest glue, time-ordered queue) ...

- difftest no longer waits for the test job; cpp clippy moves to the clippy job and
  the runner tests to the test job (both 8 vCPU), sharing a composite action that
  clones upstream, enables sccache and installs the C++ reference.
- [profile.difftest.package.difftest] opt-level = 0: the ~300k-line runner crate took
  ~5 of the ~6 build minutes at opt-level 3; solidcore stays at 3. Reports are
  byte-identical.
- difftest --jobs orders its queue by each unit's wall time in the previous run
  (reports/difftest/times.tsv, uploaded with main's reports), so the slowest unit
  starts first and the run ends at the longest unit's time.
