feat(script): implement `getOwnEnumerablePropertyKeys` for `Location`

Fixes the following assertion from `tests/wpt/web-platform-tests/html/
browsers/origin/cross-origin-objects/cross-origin-objects.html`:

    assert_equals(Object.keys(win.location).length, 0,
                        "Object.keys() gives the right answer for cross-origin Location");
