tdf#135078: let vclcanvas::SpriteCanvas implement css::lang::XServiceInfo
In Skia mode, OGLTransitionerImpl::initWindowFromSlideShowView obtains
vclcanvas::SpriteCanvas from passed xView; it's passed to getDeviceInfo,
which needs a css::lang::XServiceInfo to fill the device params sequence.
vclcanvas::SpriteCanvas did not implement it, the sequence stayed empty,
and dereferencing its elements later crashed.
When Skia is disabled (VCL:win), xView provides a dxcanvas::SpriteCanvas
instead, which implements css::lang::XServiceInfo.
This makes vclcanvas::SpriteCanvas implement css::lang::XServiceInfo.
I don't know if it's better to find out why vclcanvas::SpriteCanvas is
used in Skia mode, and not dxcanvas::SpriteCanvas.
