Promote backingstore image format to alpha
Like xcb does since 1bcfc3de7586ddb9f5d1b778b97b26ae3dc9584d.
For TranslucentBackground (ARGB32_Premultiplied) there is no change
in practice. For RGB32 we will promote to ARGB32_Premultiplied
but everything should behave like before, except that we do not rely
on undefined behavior anymore when QOpenGL/QuickWidget is in use. For
RGB16 this will enable QOpenGL/QuickWidget since there the hole
punching mechanism needs an alpha channel always.
