0597a2b51b Add transform/WrapArraysInStructs 
And replace the MSL writer's logic to do this with the transform.

We need to do the same thing in HLSL, and in the future GLSL too.

Partially reverts fbfde720

5d2f34ecf2 writer/hlsl: Simplify emission logic, clean up output 
And fix issues where global variables would not be emitted unless they were transitively referenced by an entry point.

This change requires crbug.com/tint/697 to be fixed before landing.

851b18b2f2 writer/msl: Emit field designators for structures 
This fixes constructors for structures that contain padding members
due to explicit layout attributes.

Also fix one test that was wrongly using an identity type constructor
for a structure.

94ac078990 writer/msl: Wrap each array type in a struct 
This allows them to be used in various places that WGSL allows, such
as function return types and parameters, and as the type of the RHS of
an assignment.

42220ba1b2 writer/msl: Hoist array and struct initializers 
Pull the HLSL transformation out to a standalone transform that can be
used by both HLSL and MSL.

The new E2E tests do not yet pass for MSL because they produce array
assignments, which will be addressed in the next patch.
