clone: properly exclude rev-branch-cache from post clone cache warming When adding "CACHE_REV_BRANCH" to "CACHES_ALL" in e51161b12c7e, I did not expected it to impact the clone steps. However the "CACHES_POST_CLONE" set is created rather creatively. (we should fix that, but not on stable) The benchmark caught a quite significant slowdown one hardlink and ssh-stream clones. Such slow down can be reduced to around ~5% by fully warming the cache before the clone. However keeping this expensive step away from the clone operation fully fix the slowdown and preserve the initial intend. Example slowdow for hardlink clone ### benchmark.name = hg.command.clone # bin-env-vars.hg.flavor = default # bin-env-vars.hg.py-re2-module = default # benchmark.variants.explicit-rev = none # benchmark.variants.issue6528 = default # benchmark.variants.protocol = local-hardlink # benchmark.variants.pulled-delta-reuse-policy = default # benchmark.variants.resource-usage = default # benchmark.variants.validate = default ## data-env-vars.name = netbeans-2018-08-01-zstd-sparse-revlog 6.8.2: 19.799752 6.9rc0: 29.017493 (+46.55%, +9.22) after: 19.929341 ## data-env-vars.name = mercurial-public-2018-08-01-zstd-sparse-revlog 6.8.2: 0.468020 6.9rc0: 1.701294 (+263.51%, +1.23) after: 0.471934 ## data-env-vars.name = pypy-2024-03-22-zstd-sparse-revlog 6.8.2: 2.397564 6.9rc0: 5.666641 (+137.41%, +3.28) after: 2.428085
