Ben Clayton 3cde73cb1a tint/transform/utils: Correctly scope for-loop init
When using HoistToDeclBefore on a for-loop initializer, the inserted
statement would be scoped outside the for-loop. This was incorrect.

Ben Clayton f47887d207 tint/writer/msl: Generate an array<T,N> helper
And remove the WrapArraysInStructs transform.

Wrapping arrays in structures becomes troublesome for `const` arrays, as
currently WGSL does not allow `const` structures.

MSL 2.0+ has a builtin array<> helper, but we're targetting MSL 1.2, so
we have to emit our own. Fortunately, it can be done with a few lines of
templated code.

This produces significantly cleaner output.
