Fix/unroll initializer type - #1515
Merged

Conversation
The initializer attribute carries its own copy of the type, which was left untouched while the declaration's type was unrolled. That produced mismatched declarations like `array<vec4<f32>, 8> = array<vec8<f32>, 4>()`, which fail to compile since no WGSL backend has `vec8`. Rebuild `ZeroAttr` initializers with the unrolled type on both the in-place path (array shape changes, size stays the same) and the split path (one wide declaration becomes several narrow ones).
