Backport "turnip: consider HW limit on number of views when apply multipos opt" to Mesa 21.0

Samuel Iglesias Gonsálvez requested to merge samuelig/mesa:turnip/backport-turnip-patch-21.0 into staging/21.0

Blob doesn't apply multipos optimization starting from 11 views even on a650, however in practice, with the limit of 16 views, tests pass on a640/a650 and fail on a630.

Fixes tests: dEQP-VK.multiview.draw_indexed.max_multi_view_view_count dEQP-VK.multiview.input_attachments.max_multi_view_view_count dEQP-VK.multiview.masks.max_multi_view_view_count dEQP-VK.multiview.multisample.max_multi_view_view_count dEQP-VK.multiview.queries.max_multi_view_view_count dEQP-VK.multiview.renderpass2.index.fragment_shader.max_multi_view_view_count dEQP-VK.multiview.secondary_cmd_buffer.max_multi_view_view_count

Fixes: 8d275778 ("tu: Enable multi-position output")
