Remove QWindowPrivate::compositing

It was added for Android in a4f50269f82695fbd0dd344f87b4b355feff4333,
for the case of QSurface::RasterGLSurface, but since 6.4 we no longer
use QSurface::RasterGLSurface for composition. And the Android usage
was removed in 2020ce5fd2478389c56f34742fdeee9cd24ca8a5.

Pick-to: 6.7 6.6 6.5
