Subject: [PATCH] Add tree artifact metadata for the coverage post-processing
 spawn.

This makes --experimental_split_coverage_postprocessing work in the wake of https://github.com/bazelbuild/bazel/commit/fb6658c86164b81205a056a9a54975a62f2f957a: before, it was enough to add the metadata of the tree file artifacts to the metadata provider of the post-processing action, but that change made the metadata of the tree artifact necessary, too.

Progress towards #20753.

RELNOTES: None.
