Some of our asserts and other checks depend on the total set of stages,
not just the stages set in the current pCreateInfo. Recording the stage
mask lets us combine them in vk_graphics_pipeline_state_merge().

Instead of having stencil writes as an out parameter of the optimization
function, we add a new write_enable field for stencil that's equivalent
to the similarly named field for depth. This doesn't mean drivers must
actually support disabling stencil writes independently but the
information may be helpful on some hardware.
