    Revert "meson: Add schemasdir and giomoduledir to gio dependency"
    
    This reverts commit 5aa03882cac8878d92aea26124d2a1ee8bc7e543.
    
    It fails to compile on newer Meson versions with
    `--fatal-meson-warnings` due to:
    ```
    WARNING: Project targeting '>= 0.52.0' but tried to use feature introduced in '0.54.0': variables arg in 
declare_dependency.
    gio/meson.build:833:0: ERROR: Fatal warnings enabled, aborting
    ```
    
    That happens regardless of the fact that we’ve correctly limited the use
    of the `variables` argument to only when building with Meson ≥ 0.56.
    Unfortunately Meson can’t statically detect that the argument is
    conditional.
    
    Bumping GLib’s Meson dependency is too much work right now, so this MR
    unfortunately has to be reverted.
