anv: Use an actual binding for gl_NumWorkgroups
This commit moves our handling of gl_NumWorkgroups over to work like our
handling of other special bindings in the Vulkan driver. We give it a
magic descriptor set number and teach emit_binding_tables to handle it.
This is better than the bias mechanism we were using because it allows
us to do proper accounting through the bind map mechanism.
