Fix Clang compiler warnings (-Wrange-loop-analysis)

In a macOS environment, Clang throws a number of compiler warnings
about loop variables when building qtbase.

See task for more info about the environment.

This changes a handful of loop variables,
like QJsonValue references into QJsonValueRefs.

Task-number: QTBUG-87216
Pick-to: 5.15
