nir: Add nir_lower_multiview pass

Graphics / Mesa 3D Graphics Library / Mesa - Connor Abbott [gmail.com] - 29 September 2020 10:31 UTC

Taken mostly directly from the anv pass. A few anv-specific things that I could leave in anv aren't included. Specifically on turnip we don't need to set gl_Layer to 0, and we can handle the case where the FS reads gl_ViewIndex, so that check is moved into anv.
