Vulkan: Add PipelineDesc. The PipelineDesc class is a 512-byte packed description of the entire Vulkan pipeline state. It uses the alignas keyword and some static asserts to verify that the structures are packed. This ensures that when ANGLE uses MurmurHash to hash the entire struct, and memcmp to check for identity, that there are no garbage padding bits. This CL does not implement the Pipeline cache, but it will help, since now we have a packed type that can be used as the key to a hash map.
