[PATCH v3 0/2] MR8862: mmdevapi/tests: Rewrite capturing tests.

[Giovanni Mascellani (＠giomasce)]

I began working on this to address some flakyness (see e.g. https://gitlab.winehq.org/wine/wine/-/jobs/183916), and eventually I ended up rewriting `test_capture()` because the previous implementation looked somewhat incomplete.
