Android: fix Android assets handler not listing dirs with only sub dirs
It looks like AAssetDir_getNextFileName is not enough.
Directories that contain only other directories (no files)
were not listed.
On the other hand, AAssetManager_openDir() will always return a
pointer to initialized object (even if the specified directory does not
exists), so we can't just leave only it here.
Using FolderIterator as a last resort. This approach should not be too
time consuming.
As part of this fix, add some unit tests to cover/ensure assets
listing/iterating works as expected.
Fixes: QTBUG-107627
Pick-to: 6.4 6.2 5.15
