Ban transform feedback and blend extensions with PLS

Transform feedback can lead to render pass breaks in the Vulkan backend.

EXT_blend_func_extended may restrict the number of draw buffers
depending on API state, which can invalidate a PLS implementation.

KHR_blend_equation_advanced does not allow multiple draw buffers, which
is required by some PLS implementations.
