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.
