Transform any SPIR-V that has an array with a custom stride:
@stride(S) array<T, N>
into:
struct strided_arr {
@size(S) er : T;
};
array<strided_arr, N>
Also remove any @stride decorations that match the default array stride.

Deprecate the old syntax. Migrate everything to the new syntax.

Don't generate them either, which generated a lot of test churn.

These are no longer necessary and will soon be deprecated and removed.

Change ast::Array to use an ast::Expression for its `size` field. The
WGSL frontend now parses the array size as an `primary_expression`,
and the Resolver is responsible for validating the expression is a
signed or unsigned integer, and either a literal or a non-overridable
module-scope constant.
The Resolver evaluates the constant value of the size expression, and
so the resolved sem::Array type still has a constant size as before.

- When storing to sample_mask output, write to the 0th element
- Only make a return struct if it has members
- Adjust type signedness coercion when loading special builtins.
- Adapt tests
- Update expectations for end-to-end tests
- Handle sample_mask with stride
Input variables normally don't have layout. But they can have it
up through SPIR-V 1.4.
Handle this case in the SPIR-V reader, by seeing through the
intermediate alias type created for the strided array type.
