Use the real anisotropic filtering value in Vulkan

Browse source 
When creating the Vulkan texture samplers, make them have the real
anisotropic filtering value selected by the user. This has two side
effects:

* We no longer need two sets of texture samplers in Vulkan (one with and
  another one without anisotropic filtering).

* The anisotropic filter value in Vulkan is no longer an on/off switch
  and we use the value as chosen by the user.

dependent on the GPU driver, most of them support `1`, `2`, `4`, `8`
and `16`. Anisotropic filtering gives a huge improvement to texture
quality by a negligible performance impact.
If vulkan render have used, flag is only toggle anisotropic filtering
without use specific level.

samples depends on the GPU driver, most drivers support at least `2`,
