Vulkan: Add WeakPtr to mirror std::weak_ptr This is a follow up from previous CL crrev.com/c/5938947. Because of pool eviction is based on reference count, there is need to have a weak pointer to the reference counted pool that does not add an extra reference count. This CL adds WeakPtr that works similarly to std::weak_ptr, and replaced direct RefCountedDescriptorPool pointer with WeakPtr wrapper. This is safer than RefCountedDescriptorPool in a way that it does not allow modification of underline reference count. Also the use of WeakPtr has been reduced to minimum in this CL.
