Accepting request 1073121 from GNOME:Next

- Update to version 2.12.0:
  + Add track_object(), deprecate track_obj().
  + Examples, tests:
    - examples/member_method: Make on_print() non-virtual.
    - test_limit_reference.cc: Don't use auto where a slot is
      required.
  + Build:
    - Meson:
      . Avoid configuration warnings.
      . Detect if we build from a git subtree.
      . Simplify lookup of python command.
      . Add build_tests option.
    - Meson, MSVC: Compensate for the lack of
      msvc_recommended_pragmas.h.
    - Fix build with -Dbuild-deprecated-api=false.
