QDebug: make toString() SCARY
Extract the non-template-dependent code into an out-of-line function
and pass the actual streaming operation as a callback.
Saves 4% (174811→167936) in executable size for tst_qdebug and 2.7%
(93639→91122) for tst_tostring on Linux GCC 9 AMD64 release builds.
Pick-to: 6.8
