ci: drop wait_for_smoke gates; PR workflows fire in parallel with smoke

The wait_for_smoke job (composite action that polls Smoke Test on the
PR head SHA) was forcing every other PR workflow to wait for smoke
before kicking off. End result: smoke + multi-compiler + sanitizers
were serialized when they could be parallel.

What we wanted from this gate -- "don't burn CI on a broken build" --
isn't actually saving much. Smoke takes the same wall time as the
shortest other workflow, and PR-mode draft-skip already prevents the
sweep on WIP PRs. The gate was holding back the open-PR signal more
than it was saving runner-minutes.

Strip it everywhere:
  - simple, cmdline, fips-ready, openssl-version, seed-src,
    multi-compiler, sanitizers
  - the OSP workflows already had it removed in the nightly move.

Draft-skip stays. Smoke itself still runs on PR -- it's just no longer
a barrier in front of everything else.

The .github/actions/wait-for-smoke composite action stays in the tree;
nothing references it now, but it's small and harmless to keep around
in case someone wants to opt a specific workflow back into it.
