Implement data packing intrinsics 

* Fix how the HLSL writer determines how to use a RWByteAddressBuffer
* Fix how the HLSL writer decides the register space for a storage
  variable
* Fix inference of hlsl format in the tint executable
* Add support for data packing intrinsics
  * type determination
  * validation
  * writers
  * spirv reader

Bug: tint:340, tint:473, tint:474
