fbcode_builder: regenerate non-rebalancer OSS CI workflows

Summary:
Refresh the regenerated GitHub Actions yml files for cachelib, eden(fs)/mononoke/sapling, edencommon, fb303, fizz, folly (incl. shared-libs), katran, openr, proxygen, quic (mvfst), rust-shed, wangle, watchman, and xplat fbthrift to match what `fbcode/opensource/fbcode_builder/getdeps/facebook/update-all-github-actions.sh` currently emits. No source manifest or generator changes — just `update-all-github-actions.sh` output that had drifted out of sync with the committed yml.

Net effect across these workflows:
- Enables sccache (`mozilla-actions/[email protected]`) and threads `--extra-cmake-defines '{"CMAKE_CXX_COMPILER_LAUNCHER":"sccache"}'` through every dep build step. None of these projects had sccache previously.
- Adds `Show runner info` step (CPU model, core count, free memory) at the top of each build job to help diagnose runner heterogeneity.
- Adds `Show sccache stats` and `Show GitHub Actions cache usage` post-build diagnostic steps.
- Adds the `actions: read` permission, `SCCACHE_GHA_ENABLED: on` env, and `timeout-minutes: 60` where the generator now emits them.

Cachelib's `actions/upload-artifact@v6` was preserved at `v7` — the generator default is `v6` and everywhere else already matches, but cachelib was hand-bumped to `v7` and we're not rolling that back as part of this regen pass.
