QNX: Remove most of the CPU overhead for video rendering
This patch uses the GL_OES_EGL_image extension to create a OpenGL Texture handle
for a libscreen pixmap. If the extension is not available it uses the "old"
technique as fallback where the image data is copied into a QImage.
This reduces the CPU load by more than 70% and allows HD videos to be played jitter-free.
Task-number: QTBUG-37752
