Show file ownership and safe.directory entries on every test job

Add a step to each workflow that runs the test suite that prints the
ownership (NTFS Owner / POSIX uid+gid) of key paths -- the workspace,
its `.git`, the gitdb and smmap submodule worktrees and gitfiles, the
runner's home directory, and `~/.gitconfig` -- as well as the full
list of `safe.directory` entries at that point.

GitPython's tests are intentionally coupled to the layout and state of
the GitPython repository they run against; ownership and the trust-
config that gates whether git will operate on a path are part of that
state. Surfacing them in every test job gives diagnostics to read
alongside any failure that turns out to be a setup problem rather
than a code defect.

The step is added to:

- `cygwin-test.yml`'s `test` job, with a YAML anchor
  (`&ownership-display`) so the temporary `reproduce-safe-dir` matrix
  job can reuse it via `*ownership-display`.
- `pythonpackage.yml`'s `test` job (Linux/macOS/Windows-native).
- `alpine-test.yml`'s `test` job.

It runs after `init-tests-after-clone.sh` has populated the submodules
and after `safe.directory` has been configured (in workflows that
configure it), so the values reported are what the tests will see.
