anv: use shadow surface for stencil input attachment on gfx7 

This fixes a number of tests like :
  dEQP-VK.renderpass*.suballocation.multisample.s8_uint.*
  dEQP-VK.renderpass*.suballocation.multisample.separate_stencil_usage.d24_unorm_s8_uint.*.test_stencil
  dEQP-VK.renderpass*.suballocation.multisample.d24_unorm_s8_uint.*
  dEQP-VK.renderpass*.suballocation.multisample.d32_sfloat_s8_uint.*

Because the driver asserts when generating RENDER_SURFACE_STATE with a
8 Valign value for stencil buffer (only 2 & 4 are supported).
