anv/pipeline: Set tess IO read/written key fields in compile_*

We want these to be set as close to the final compile as possible so
that they are guaranteed to happen after nir_shader_gather_info is
called.  The next commit is going to move nir_shader_gather_info to
after the linking step which makes this necessary.
