Volker Hilsheimer aa45401ffb QPalette: always increase serial number when modifying
After 109e088c7c5d0c9325966e88d55fd9f7a58f67ea, cache keys were unique
for palettes with different private or data instances, but the key did
not change when a palette without any shared copies was modified, as
that does not create new private data structures.

To fix this, always increase the counter for the private data structure,
also when not detaching from shared copies.

Augment test case with scenario that broke.

Fixes: QTBUG-108709
