Dennis Klein f374e228ff ci: cache gcc as a buildcache node instead of committed lockfiles
Committed lockfiles pinned gcc as a host-path external (from spack compiler
find), which is not portable across runners and broke CI. Cache the gcc
compiler itself as a buildcache node instead, so CI pulls it (~1 min) rather
than building it from source (~1 h).

- push the freshly-built gcc node in setup-deps BEFORE spack compiler find
  (which marks it external and excludes it from buildcache push), gated behind
  a push-gcc input used only by the buildcache workflow
- drop the committed-lockfile approach: remove test/ci/locks, the lockfile
  install path in setup-deps, and the lockfile export in the buildcache workflow
- drop the ignored ref input from setup-spack (v3 renamed it to spack_ref)
