writer/msl: Hoist array and struct initializers

Browse Source 
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.

Fixed: tint:826
