Make text node scenegraph API public

A lot of functionality is hidden underneath this, so exposing
this API will make it possible to build custom text-based
components for Qt Quick.

[ChangeLog][Text] Added QSGTextNode and QQuickWindow::createTextNode()
for creating scene graph nodes containing text. This can be useful when
building custom Qt Quick items with text.

Fixes: QTBUG-72773
