James Price 4d3af66bbd tint/msl: Preserve trailing vec3 padding 
In order to preserve padding properly for MSL, we need to use its
packed_vec type for all vec3 types in storage buffers, not just struct
members. This commit includes a complete rewrite of the PackedVec3
transform to achieve this. The key details are:

* An internal `__packed_vec3<>` type was added, which corresponds to a
  `type::Vector` with an additional flag to indicate that it will be
  emitted as packed vector.

* The `PackedVec3` transform replaces all vec3 types used in
  host-shareable address spaces with the internal `__packed_vec3`
  type. This includes vec3 types that appear as the store type of a
  pointer.

* When used as an array element, these `__packed_vec3` types are
  wrapped in a struct that contains a single `__packed_vec3`
  member. This allows us to add an `@align()` attribute that ensures
  that `array<vec3<T>>` still has the correct array element stride.

* When the `vec3<T>` appears as a struct member in the input program,
  we apply the `@align()` to that member to ensure that we do not
  change its offset.

* Matrix types with three rows that are used in memory are replaced
  with an array of columns, where each column uses a `__packed_vec3`
  inside an aligned wrapper structure as above.

* Accesses to host-shareable memory that involve any of these types
  invoke a "pack" or "unpack" helper function to convert them to the
  equivalent type that uses `__packed_vec3` or a regular `vec3` as
  required.

* The `chromium_internal_relaxed_uniform_layout` extension is used to
  avoid issues where modifying a type in the uniform address space
  triggers stricter layout validation rules.
