iris: slow clear higher miplevels on single sampled 8bpp resources that have TILE64

Browse source 
This helps fix a number of piglit tests that exercise this
functionality, such as:
  - piglit.spec.arb_texture_rg.fbo-clear-formats
  - piglit.spec.ext_framebuffer_object.fbo-clear-formats
  - piglit.spec.ext_texture_snorm.fbo-clear-formats
