Extend and improve tst_customization

Add more test cases, and clarify the roles of the test styles.
- empty: no delegates at all
- incomplete: has all delegates, but with no bindings that access
  delegates and therefore trigger creation (tests that delegates must
  be created regardless)
- simple: has all delegates and creates bindings to simulate a full
  style
- override: overrides the simple style and tests that the default
  instances of overridden delegates are not created

There are still several non-popup controls that lack deferred
execution. These are marked with QEXPECT_FAIL() to make it easy
to track what's missing. This list still excludes all popups.
