Add literal operators for QLatin1String and QLatin1Char

The operators are declared in the Qt::Literals::StringLiterals
namespace, to avoid collisions in the global namespace.

[ChangeLog][QtCore][QLatin1String] Added literal operator""_L1 that
converts string literals and chars to QLatin1String and QLatin1Char.

Fixes: QTBUG-98434
