ivigenerator: Use QStringLiterals for string default_values

For default_values in our simulation backends, QLatin1String() were
generated so far, but when using these for initializing a struct
with only one string property, this caused problems, as the structs
are using QStrings and because of an additional QVariant constructor
this caused some ambiguity for the compiler.
Switching to QStringLiterals fixes this problem, as the QString
constructor is used in this case.
