  Vulkan: Refactoring to use ProtectionType enum instead of bool
  
  This is a second stage of refactoring that was started here:
      Vulkan: Minor CommandQueue implementation refactoring.
      0210b46d35b51ea04bddafb48ba406a87c39e58e
  
  Enumeration renamed: CommandContent -> ProtectionType.
  
  Currently interfaces of ContextVk/RendererVk/CommandQueue use
  "hasProtectedContent" boolean. Internally CommandQueue uses
  "vk::ProtectionType" enumeration to separate states related to
  Unprotected/Protected commands. This CL replaces boolean with
  enumeration for consistency.
