This CL changes the MSL emission for struct initializers to emit the
struct name first.
`const a = {.f=float3(1)}` becomes `const a = Normals{.f=float3(1)}`.
This fixes an issues where the initialization happens inside an array
which the downstream compiler rejected without the explicit struct
naming.
