Clément Foucault 7710de26d0 Workbench: Depth Of Field: Fix undefined behavior with using texelFetch
On MacOS + Intel Iris Graphics 6100 (may affect other config too), the
texelFetch operation bypass the base mip setting of the texture object.

Using textureLod with lod = 0.0 ensure the lowest (after clamping) mip will
always be selected.

Also disable the texture filtering for this sampler to avoid unecessary
fetches.

This should fix T78653 Blender 2.83 broken Depth of Field in Viewport
