    anv/GetQueryPoolResults: Actually implement the spec

    The Vulkan spec is fairly clear about when we should and should not
    write query pool results.  We're also supposed to return VK_NOT_READY if
    VK_QUERY_RESULT_PARTIAL_BIT is not set and we come across any queries
    which are not yet finished.  This fixes rendering corruptions on The
    Talos Principle where geometry flickers in and out due to bogus query
    results being returned by the driver.  These issues are most noticable
    on Sky Lake GT4 2hen running on "ultra" settings.
