Until now the Vulkan backend supported a single pre-configured sampler.
This PR realizes creation, caching and freeing of samplers based on what
is required by the state manager.
The implementation is similar to OpenGL or Metal. This fixes many issues
including:
- Textures in workbench and eevee use the correct extend and filtering
- Custom icons render correctly
- Depth sampling issues
- Removes artifacts using EEVEE world shader, lighting and indirect lighting.
