gl-renderer: Use pnode is_opaque when drawing 

We test if the surface is fully opaque during paint node updates, and
store that information. Now that we've refactored the blended calculations
a little bit, we can easily use this test to make paint_node->is_opaque
override the blend calculation entirely.

This is preparation for future patches that will override is_opaque
when performing content censoring or fallback rendering of solid colors
for weston_direct dmabufs.
