CMake: Add debug information for 'qt_evaluate_config_expression'
Add '_qt_internal_dump_expression_values' function that dumps all
values evaluated by 'qt_evaluate_config_expression'.
'_qt_internal_dump_expression_values' doesn't evaluate undefined
features, only collect actual values.
Fixes: QTBUG-88476
