rhi: gl: Switch back to Nearest filtering when resolving
...for Qt 5 compatibility. It seems both Qt Gui and Quick calls
the QOpenGLFramebufferObject helper for blitFramebuffer with
the default GL_NEAREST argument for the filtering. In Qt 6 we
must use the same if we want to ensure pixel-perfect compatibility.
Pick-to: 6.6 6.5
Task-number: QTBUG-113811
