Put the uncached GTT type at a higher index than the visible VRAM type,

When we don't have dedicated VRAM, we don't have a non-visible VRAM

According to the spec, for types with identical flags, we should give
the one with better performance a lower index.

Previously, apps which follow the spec guidance for choosing a memory

anv: Only re-emit non-dynamic state that has changed.

On commit f6e7de41d7b, we started emitting 3DSTATE_LINE_STIPPLE as part
of the non-dynamic state. That gets re-emitted every time we bind a new
VkPipeline. But that instruction is non-pipelined, and it caused a perf
regression of about 9-10% on Dota2.

This commit makes anv_dynamic_state_copy() return a mask with only the
state that has changed when copying it. 3DSTATE_LINE_STIPPLE won't be
emitted anymore unless it has changed, fixing the problem above.
