nir: Add nir_intrinsic_texture_base_agx sysval

For non-bindless textures, get the base address of the texture
descriptor array, so we can crawl descriptors in the shader. For
bindless, this isn't needed (since the bindless handle will be the
address itself).

jekstrand suggested the idea of the descriptor crawl. It worked out
pretty well, all considered.
