  Vulkan: Switch SamplerBinding to Use SharedPtr
  
  Another step to remove vk::BindingPointer. SharedPtr is used and
  SamplerBinding is renamed to SharedSamplerPtr. This also removed
  RefCountedSampler to avoid direct expose of RefCounted<SamplerHelper>
  which is risky due to ability of change reference count directly.
