72029b678a Empirical attempt at fixing #15661 
Basically, software culling fails in some configuration, like the one we
end up with on Mali.

As noted by unknownbrackets in #15661, the viewport Z scale, offset is -0.0, 0.0.

We end up with CalcCullParams computing minZValue == maxZValue == 1.0f,
and with the vertices ending up with z,w == 1.0, 1.0.
and as a result, the inside/outside calculations will always decide that
it's outside.

Changing the comparisons from >= / <= to > / < fixes the problem, but I
don't know if this might break something else.

Anyhow, here's the simple way to repro on PC:

Change the ending of GPU_Vulkan::CheckFeatures to:

```c
	return GPU_USE_LIGHT_UBERSHADER | GPU_USE_BLEND_MINMAX | GPU_USE_TEXTURE_NPOT | GPU_USE_INSTANCE_RENDERING |
		GPU_USE_VERTEX_TEXTURE_FETCH | GPU_USE_TEXTURE_FLOAT | GPU_USE_16BIT_FORMATS | GPU_USE_TEXTURE_LOD_CONTROL |
		GPU_USE_DEPTH_TEXTURE | GPU_USE_ACCURATE_DEPTH;
```

GPU: Remove explicit rect/line depth cull. 
This appears to be breaking NFS (#15129) and isn't fully correct since
the triangles are still later checked anyway.

ea1f0a1195 Vulkan: Match safe size behavior on all backends. 
Before, we would not mark a safe size for some Vulkan clears where depth
was not cleared, deviating from other backends.  We also never detected
that on PowerVR.  This makes things more consistent.
