sna: Hint whether we prefer to use the GPU for a pixmap
This includes the condition where the pixmap is too large, as well as
being too small, to be allocatable on the GPU. It is only a hint set
during creation, and may be overridden if required.
This fixes the regression in ocitysmap which decided to render glyphs
into a GPU mask for a destination that does not fit into the aperture.
