anv: skip acceleration structure in binding table emission

With mutable descriptor types, we can end up in a situation where a
binding can be, for instance, both a UBO and an acceleration
structure.

While we can promote the UBO to a binding table entry and the shader
can use it, this isn't true of acceleration structures that have no
surface state. In that case just skip the entry. The shader is already
compiled to use the descriptor entry.

In the non mutable case, the entry will not be created by
anv_nir_apply_pipeline_layout.
