When --experimental_remote_merkle_tree_cache is set, Merkle tree calculations are cached for each node in the input NestedSets (depsets). This drastically improves the speed when checking for remote cache hits. One example reduced the Merkle tree calculation time from 78 ms to 3 ms for 3000 inputs. The memory foot print of the cache is controlled by --experimental_remote_merkle_tree_cache_size. The caching is discarded after each build to free up memory, the cache setup time is negligible. Fixes bazelbuild#10875. Closes bazelbuild#13879. PiperOrigin-RevId: 405793372
