[docs] Remove references to C++11 feature availability

QVersionNumber, e.g., was added for Qt 5.6, the last Qt version that
didn't require C++11. So it made sense that the original documentation
stated that certain functions were only available in C++11 mode.

But already Qt 5.7 required C++11, so these historical anecdotes are
no longer pertient to today's Qt users, so remove them from the docs.

Pick-to: 6.7 6.6 6.5 6.2 5.15
