Fix -trace build on Windows

The TraceLoggingValue template does not have overloads for Qt
types, so it was throwing multiple template instantiation errors
while trying to log the unknown types.
Fix it by serializing such types to QString using QDebug::toString,
and the logging this string.

Apart from that, fixes some other compiler errors on Windows build
with -trace enabled:
- implicit size_t to ULONG conversion
- complaints on std::min
- add QT_BEGIN_NAMESPACE/QT_END_NAMESPACE to the generated
  *_tracepoints_p.h headers to fix the namespace build.

Task-number: QTBUG-97246
Fixes: QTBUG-97241
Pick-to: 6.2
