The platform backingstore might need access to the window that the
backingstore was created for, e.g. for makingCurrent to release OpenGL
resources. In that case leaving it to the QRasterWindowPrivate destructor
would be too late, as the QWindow was gone.
This was seen on iOS, where the backingstore inherits QRasterBackingStore,
and uses composeAndFlush to composit via GL. The raster backingstore
cleans up these GL resources in its destructor, so the QIOSBackingStore
destructor makes sure that the GL context is current for the window,
resulting in a crash since the window is long gone by then.

Instead of the never-ending blacklisting of "broken" drivers, simply switch
to always choosing a byte ordered QImage format with OpenGL ES, and keep
on using the (one and only) spec-mandated GL_RGBA/GL_UNSIGNED_BYTE combo.
There is nothing broken with not supporting BGRA for glReadPixels even when
GL_EXT_read_format_bgra (an out of date, pre-2.0 extension that got folded
into the spec to begin with) is present. We do not have a good way to tell
if BGRA_EXT is supported for glReadPixels or not, so just skip the whole
problem altogether.
