Reduces the overhead per call of lookupId() from around 7000 to 180
instructions for a use case. Should in general scale much better.
I still do not like that this is using global static data that is
never cleaned up. It should be tied at the minimum to the lifetime
of the Qt 3D scene.

About 50% of callers pass static string literals,
which can be converted from QStringLiteral to
QLatin1String if by adding the overload.
Because of the complicated logic in the existing
overload, no attempt is made in this commit to
hand down the QLatin1String until the actual
comparison. Instead, the QString overload is
called, for now.
Saves almost 1KiB in text size in Render on
optimized GCC 6.0 Linux AMD64 builds.

Provides a non negligible gain in performance.
