[8.5.0] Do not download in-memory outputs

The documentation for `--experimental_inmemory_dotd_files` and `--experimental_inmemory_jdeps_files` states '_...instead of being written to disk_', but the files were actually written to both memory and disk (unless combined with BwoB). This caused two problems:

1) Unnecessary overhead from **remotely downloading** all in-memory files **twice**.

2) Paradoxically **reduced robustness of `--remote_download_all`**: that flag normally increases Bazel’s resilience to remote cache issues, but because these outputs were kept in memory instead of being written to disk by RemoteSpawnCache.lookup (which handles cache issues gracefully), action finalization treated them as missing on disk and attempted a more fragile download, increasing the risk for "_unable to finalize action_" failures (see #22387).

This change ensures that in-memory files are kept exclusively in memory and are not written to disk. This aligns with the documentation and addresses both problems.

Fixes #22387

Closes #26898.
