Disable switchable widget compositing when using XCB in Parallels VM
The Parallels 3D hardware acceleration does not seem to play nice with
Qt Creator when switching between tabs that have OpenGL Qt Quick Content
and those that have just raster widget content. QWidgetBackingstore has
the ability to switch how content is flushed depending on if the
SwitchableWidgetComposition capability is available. Previously for XCB
it was always enabled, but should be disabled when using the GLX
integration for the Parallels VM.
