tst_QImageWriter: clean up

- port Q_FOREACH to C++11 range-for
- port uses of inefficient QLists to QVector or C arrays
- port uses of dynamic containers with static content, to constexpr
  C arrays
- fix algorithmic mistakes:
  * use adjacent_find with greater<> to emulate C++11 std::is_sorted
    instead of sorting the range and comparing it with the original
    (and not even using stable_sort to do this).
  * use std::unique == end() to detect absence of duplicates instead
    of poplulating a QSet and comparing its size with that of the
    original range.
  * use a simple QCOMPARE instead of populating a QSet with statically-
    known content, removing known options to be able to check that the
    remaining options are unknown

Fixes errors pointed out by my tree's static checks.
