Bug 14583: Remove VkBufferView for UBO/SSBO descriptor types

For descriptor types:
VK_DESCRIPTOR_TYPE_UNIFORM_BUFFER
VK_DESCRIPTOR_TYPE_STORAGE_BUFFER
VK_DESCRIPTOR_TYPE_UNIFORM_BUFFER_DYNAMIC
VK_DESCRIPTOR_TYPE_STORAGE_BUFFER_DYNAMIC
No longer need to create a VkBufferView, instead can
put the buffer, offset and range directly into a descriptor.
Many places in the driver assumed it could point to a persistent
buffer view and that is no longer the case. Now cache the
view info rather than a pointer to deal with that.
