Make QSGMaterialRhiShader become QSGMaterialShader

After a symbiotic relationship in Qt 5.14 and 5.15, it is time for
QSGMaterialRhiShader to devour its older sibling and take its place.

This makes the direct OpenGL rendering path disfunctional. All
QSGMaterial Qt 6 TODOs are solved, the API is clean and straightforward
again: a QSGMaterial creates a QSGMaterialShader, no special flags and
options needed. (it's just that QSGMaterialShader now has a slightly
different API)
