#13126 RiaLogging: Take std::string_view for logElapsedTime message

Switch the message parameter from const QString& to std::string_view so
callers with std::string in hand no longer need a QString::fromStdString
wrapper. The internal duration formatting still uses QString::arg, fed
from a single QString::fromUtf8 conversion.

Callers passing QString locals are updated with .toStdString() at the
call site.
