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.

Aside from more SPIR-V using OpConstantNull, this is a no-op change.
By refactoring these methods, they're easier to read, and contain less
lambda-heavy code.

This CL updates all of the Tint unittests to the new @stage shorter
syntax. This also updates the WGSL writer to emit the new short forms
instead of using the deprecated form.

This is required to handle materialized values, and for constant

Concatenating strings to use for cache keys is horribly inefficent and very error prone.
Add a UnorderedKeyWrapper helper to allow types to be used as a unordered_map and unordered_set key. Use this for the type_constructor_to_id_ map.
Produces SPIR-V with some duplicate SPIR-V instructions for constructors removed.

Use of semicolons is still supported, but deprecated.
Also updates the parsing methods for structures to better match the
WGSL grammar.
