[PATCH v3 0/8] A handful of Meson cleanups and improvements

Hi,

this patch series contains a couple of more-or-less random cleanups and improvements for Meson that I have accumulated over the last two months.

Changes in v2:
  - Fix an off-by-one error for test slices used in GitHub Workflows.
  - Now tested with both GitLab (https://gitlab.com/gitlab-org/git/-/merge_requests/375)
    and GitHub (https://github.com/git/git/pull/2010).
  - Link to v1: https://lore.kernel.org/r/20250703-b4-pks-meson-cleanups-v1-0-2804c2932abe@pks.im

Changes in v3:
  - Add a comment explaining why we only need to search for Python on
    the build target.
  - Link to v2: https://lore.kernel.org/r/20250708-b4-pks-meson-cleanups-v2-0-94ac53cd4b95@pks.im

Thanks!

Patrick
